1
What's New?
Changes in this Release
The KB_SQL ODBC Driver for KB_SQL Version 4 is a completely new and updated
driver designed to work with the latest applications from Microsoft, including Microsoft
Office97 and Office2000.
ODBC SDK 3.51
Driver and server compatibility
File data source names
Silent configuration options
Connection pooling
Safe threads
Multi-row fetch
Custom network support
Character set translation ODBC SDK 3.51
The version 4.0 KB_SQL ODBC driver has been updated to be compliant with
Microsoft’s latest SDK for 32-bit ODBC Drivers. Numerous performance and flexibility
improvements have been made to the driver.
Connection pooling
Connection pooling enables an application to use a connection from a pool of established
connections. If a connection has already been created and placed in a pool, an application
can use that connection without performing the entire connection process. Re-using
connections from the pool can increase performance since applications can save the
overhead involved in making a connection. This is especially significant for middle-tier
applications that connect over a network or in a situation where the application repeatedly
connects and disconnects (e.g. Internet applications).
Enabling Connection Pooling
Connection pooling can be used by an ODBC application if the application calls
SQLSetEnvAttr with the SQL_ATTR_CONNECTION_POOLING attribute. In order to
enable connection pooling with KB_SQL’s ODBC driver, it will be necessary to enable
3
KBSODBCDriver
the feature and set the timeout value via the ODBC administrator. This timeout value
determines the period of time which an inactive connection is removed from the pool.
Driver and server compatibility
We will continue to support older versions of the KB_SQL ODBC Driver that work in
the ODBC version 2.x mode. This has been accomplished by physically separating the
two versions of the Server API code, including the stored procedures for catalog
functions.
Please note that the older version of the stored procedures and SQL catalogue tables have
been renamed. Version 2.x stored procedures and SQL catalogue tables all end with “A”
(for example, SQL_SP_COLUMNSA).
Please note that although older drivers can be used with the new server, using the older
drivers will prohibit the use of new server features (for example, the LONG data type). In
addition, because KBS will not be providing bug fixes for older releases, we strongly
urge upgrading to the latest driver.
Special Note About the 16-bit Driver
Please note that no new development has been performed on the 16-bit ODBC driver.
The 16-bit driver is currently in maintenance mode using Microsoft ODBC SDK 2.10.
Although applications using the 16-bit ODBC driver will continue to work, they will not
be able to take advantage of any new features. File data source names
We now support the dynamic creation of file data source names from the ODBC
Administrator and Microsoft Office applications. Previous versions of the product
required that file data source names be created manually. File DSNs can be shared on
network drives and can simplify workstation configuration.
Silent configuration options
The product now supports DSN-less connections. This feature provides the ability to
connect to a remote data source without having to create a data source in the ODBC
Administrator, thus simplifying application distribution.
Safe threads
For customers that are using, or are interested in using multi-threaded applications such
as Microsoft Transaction Server, Internet Information Server, and Java, version 4.0 fully
supports safe threads. KB_SQL version 4.0 fully supports safe threads so that
applications can use the same handle on more than one thread. In a multi-threaded
environment, it is possible for each thread to have independent data. However, it is also
possible for multiple threads to share data. In this situation, the different threads must
cooperate in accessing the data.
Multi-row fetch
4
What's New?
We now support SQLExtendedFetch and SQLFetchScroll. In ODBC 3.0,
SQLFetchScroll has replaced SQLExtendedFetch. These calls allow an application to
retrieve multiple records at one time thus reducing the number of calls between the
application and the driver.
Custom network support
Version 4 separates the client, network, and setup API functions so that each can be
developed independently. Because the components are separated, customers have the
option to develop custom network interface modules based on their networking or
security conventions.
Contact KBS technical support for more information on how you could implement a
custom network module. Character set translation
Prior to this release, ANSI to OEM character translation was performed on the server side
by specifying the translation rules in the site global. With version 4.0, character set
translation is performed on the driver side. To implement the character set translation, it
will be necessary to specify the appropriate translation DLL for the data source name via
the ODBC Administrator.

Understanding ODBC
What is ODBC?
ODBC (Open Database Connectivity) is a standard interface developed by Microsoft for
accessing data from different kinds of SQL database management systems. See
www.microsoft.com/data for additional information.
What does this mean to the M Community?
•
•
•
This means that you can use many of the Windows applications already on your
desktop to get to your M data.
With the KB_SQL Server together with the KB_SQL ODBC Driver, you can now
use the Microsoft Office programs including Excel, Word, and Access or any
ODBC-compliant Windows application to access your M data.
You have many more choices for data access and reporting of your M application
data.
How does it work?
The KB_SQL ODBC Architecture consists of six main components:
•
•
•
•
•
•
your Windows application programs
the ODBC Driver Manager
the KB_SQL ODBC Driver
networking software (TCP/IP)
the KB_SQL Server Interface
the KB_SQL Engine and relational data dictionary
The KB_SQL ODBC Architecture
•
•
•
•
Resident on your workstation, the client side, you need your Windows
applications, the ODBC Driver Manager, the KB_SQL ODBC Driver, and the
networking software.
Your Windows applications can be any ODBC-compliant Windows application.
They can be commercial off-the-shelf products like Microsoft’s Excel and Visual
Basic or custom applications.
Microsoft provides The ODBC Driver Manager component. Its primary function
is to load the driver. If it is not resident on your system at the time you install the
KB_SQL ODBC Driver, the setup program, on your installation disk, will install
it for you.
The KB_SQL ODBC Driver enables any ODBC-compliant Windows application
to access data from your KB_SQL RDBMS. The driver must be accessible to
each workstation that wants to use Windows applications to access the KB_SQL
Server. You can install the driver on as many workstations as you like. Access to

•
your M data is limited only by your KB_SQL license, which determines the
number of concurrent users.
Networking software is necessary to communicate between the Driver and Server.
The KB_SQL ODBC Driver requires TCP/IP networking software.
On your server, you need to install KB_SQL Server and you need to have your M
globals mapped as SQL tables into a SQL data dictionary. If you have any
previous version of KB_SQL, this has already been done.
The KB_SQL Server Interface encapsulates the Server API and Network Library
M, and exposes the KB_SQL Engine to the client.
Benefits of KB_SQL ODBC
•
•
•
•
8
You are free to select the application that is most appropriate for the task at hand.
At any point in time, you can choose to use either the EZQ or SQL Editors that
come packaged with KB_SQL, or you can select from many ODBC-compliant
Windows applications.
You can continue to access your M data from a terminal or choose a workstation
that has access to a KB_SQL ODBC Driver.
KB_SQL ODBC simplifies application development. You can write a single
application that can be used to extract data from many different databases,
permitting maximum interoperability and portability of the application.
With KB_SQL ODBC, accessing M is like accessing any other RDBMS.
Actually, the fact that you may be accessing different types of databases
concurrently is transparent to you.
Driver Installation and Setup
Before you begin
Before installing the KB_SQL ODBC Driver, there are a couple of items to note.
•
•
•
•
Is the Server installed and configured?
Do you know the Server configuration parameters for the Hostname (or IP
address), and listening port?
Can you ping the Server using the Hostname (or IP address)?
If running WindowsNT, do you have Administrator privileges?
Driver Installation
Step 1: Launch the KB_SQL ODBC Driver Installer.
Step 2: Accept the terms of the license agreement.
After accepting the terms, the installer will update your system with the KB_SQL ODBC
Driver and other ODBC Components.

Server and Network Configuration
Server Info
ServerInfo
Prefix for stored query routines
Maximum number of stored queries
Allow connections
Trace API calls
Edit network configuration
Server initial execute
Server user initial execute
Prefix for stored query routines
Assign a name to the holding place for the last x number of queries run. For example, if
you enter XA, the Server API allocates routine names starting with XA1 up to the
maximum number of stored queries specified.
Maximum number of stored queries
13
KBSODBCDriver
Enter the number of queries that you want held in the stored queries buffer on the server.
The value you supply is a matter of storage space versus processor resources. Assigning a
large number requires more storage capacity but less processing time. Conversely,
assigning a smaller number requires less space to store queries, but causes more
processing by the SQL engine. Here’s why: As the Server API receives each SQL
command, it checks the stored queries buffer for the command’s corresponding M
routine. If it finds the M routine, it simply runs it. If it doesn’t, it has to use the SQL
engine to translate the command into one or more M routines. The M routine and
corresponding SQL command are then stored and assigned a routine name using the base
routine prefix. If you specify a large number, say 999, many commands can be processed
before having to reuse a stored query for another command. When the maximum number
has been reached, KB_SQL reuses the oldest stored query to store the next query’s M
routine and corresponding SQL command. You may clear the stored queries buffer of all
routine names by invoking the RL^SQL tag.
Allow connections
Answer YES to accept connections to the server. Answer NO if you want to refuse
connections. Note that the server will not start if the system lock is set. (Refer to the
UTILITIES\LOCK STATUS option.)
If the server is running and you want to stop allowing connections, first invoke the
STOP^SQL0SVR function. Then set this prompt to NO.
Regardless of the setting of this prompt, the server can always be run in foreground—
useful for testing purposes when you don’t want the server to be started in background.
If the server is not running when you set this value to YES, you still have to start the
server. It is not automatically started. To start the server, see the instructions for starting
and stopping the KB_SQL Server later in this chapter.
Trace API calls
Answer YES if you want to track information about the dialog between the server and
clients. This creates a log that you can view by using the SQL Editor to run the
SQL_API_SERVER_TRACE query, or by using the tag VIEW^SQL0SVR.
Edit network configuration
Answer YES if you want to edit TCP/IP defaults or host information. The TCP/IP
Defaults window will appear. A discussion of this process begins on the next page.
Server initial execute
14
Enter the M code that will instantiate any variables that are required by your application
during the runtime execution of queries.
Server user initial execute
Enter the M code that will validate and/or establish the username (SQLUNAME) and
password (SQLUAUTH) variables referenced during the connection to the server.
Network Configuration
NetworkInfo
n general, the network information you are required to provide consists of the TCP/IP
host and port information. Depending on your M implementation type, you might be
required to provide alternate ports.
TCP/IP Defaults
TCP/IP Host Definition
TCP/IP Port Defintion

TCP/IP Host Definition
Host name Enter the TCP/IP hostname for the server.
IP address Enter the internet protocol address for the server. If your system uses
dynamic ip address allocation, enter the host name in this field.
Description Enter a brief description of this server.
Local host? Enter YES if you are describing the server on which KB_SQL is running.
Enter NO if you are documenting another server.

The port number is expected to be in the range of 5000-65535.
Answer YES if this is the published port for connecting to this server.
Answer NO if this is an alternate port to be used internally.
TroubleShooting
Network Troubleshooting
Troubleshooting network connections can be challenging due to complex configurations.
However, we've found that most of the errors related to KB_SQL have been incorrectly
configured servers. It is easy to check the configuration of your server using our built-in
testing tool, TEST^SQL0TCP.
In general, we try to include useful information in error message displays. As for
networking errors, we try to include the Windows Sockets (WinSock) error code as part
of the message. If you see 10061 - Connection Refused, you probably need to check that
your server is started. If you receive the error 10065 - No Route to Host, you might have
specified a host address incorrectly.
Using TEST^SQL0TCP
VMS Cluster Issues
Using TEST^SQL0TCP
There are low-level TCP/IP testing tools available through KBS technical support. If you
think you are having network trouble, please call us.
17
KBSODBCDriver
Starting with KB_SQL v3.6, we provide a simple utility to test the configuration of your
Server and Network. The TEST^SQL0TCP utility will attempt connections from your
Server back to itself, and keep trying connections until it fails.
For example:
>D TEST^SQL0TCP
KB_SQL Server Connect Test
Server Name or Address: 127.0.0.1//
Port Number : 6500//
UserName : DBA
PassWord :
Connecting to 127.0.0.1 (6500)
Error in connect: 0579: TCP/IP Timeout in Open
As the error message implies, the attempt to connect has timed out. The most likely cause
is that the server is not started.
>D START^SQL0SVR
>W $D(SQLERR)
0
This attempt to start the server is successful, as it does not return an error in the SQLERR
variable.
Now, try the connect test again.
>D TEST^SQL0TCP
KB_SQL Server Connect Test
Server Name or Address: 127.0.0.1//
Port Number : 6500//
UserName : DBA
PassWord :
Connected to #1: |TCP|5~127.0.0.1~6500 ...
Connected to #2: |TCP|6~127.0.0.1~6500 ...
Connected to #3: |TCP|7~127.0.0.1~6500 ...
Connected to #4: |TCP|8~127.0.0.1~6500 ...
Connected to #5: |TCP|9~127.0.0.1~6500 ...
Connected to #6: |TCP|10~127.0.0.1~6500 ...
Connected to #7: |TCP|11~127.0.0.1~6500 ...
Connected to #8: |TCP|12~127.0.0.1~6500 ...
Error in connect:
[S1000] (139): [Knowledge Based Systems, Inc.][Server API][V4.0]SQLConnect:
Exceeded KB_SQL V4.0 license limit
18
Disconnecting #8: |TCP|12~127.0.0.1~6500 ...
Notice that it gets 8 connections before it encounters an error. It shows that this attempt
to connect is rejected because it would exceed the current limit of your license. This is
the error that you want to get in this context. It ensures that everything is working. If you
get other errors, it is helpful to pass on the information to our technical support.
Currently, the most common problem with connecting is that the Server is not started. We
recommend adding START^SQL to your system startup logic.
The second most common problem is for those M types that require alternate ports (ISM,
DSM, and others), that not enough are configured. We always recommend configuring at
least as many ports as you have connections on your license. Configuring more doesn't
hurt either. VMS Cluster issues
On VMS clusters, it gets very tricky when starting an M process to “listen” for
connections.
The M database has a single definition of the local host.
One or more nodes can access the database.
Starting the “listener” from a node other than the one identified in the local host setting
can have confusing consequences.
One way of preventing this problem is to disable the auto startup feature using Site Edit.
Another way is to add code to the Server StartUp Execute to test whether the current
node matches the local host definition. If it doesn't, then the Server should not be allowed
to start. Simply return an error in SQLERR.
Starting the Server
Starting the Server
There are several methods available for starting the KB_SQL Server. You may start it
either in the foreground for analysis and debugging purposes or in the background for a
multi-user production environment.
Foreground Options
Background Options
Foreground
You may run the KB_SQL Server in foreground during configuration until you are
satisfied that you are able to connect and process client requests. The following
foreground options are available:
19
KBSODBCDriver
1. Output to Screen
Command:
>D ^SQL0SVR
Description: This command is for general configuration, analysis and debugging.
Sample Output:
Waiting for client connection ...
KBSGetInfoShort("1010","23") = (0,"2")
KBSGetInfoShort("1010","24") = (0,"2")
SQLAllocStmt("1010") = (0,"2007")
SQLPrepare("2007","select * from employees") = (0,"1")
SQLNumResultCols("2007") = (0,"4")
SQLDescribeCol("2007","1") = (0,"EMP_SSN","12","11","0","0")
SQLDescribeCol("2007","2") = (0,"NAME","12","15","0","0")
SQLDescribeCol("2007","3") = (0,"SALARY","2","5","2","1")
SQLDescribeCol("2007","4") = (0,"MANAGER","12","11","0","1")
SQLExecute("2007") = (0)
KBSRowsetFrame("2007","1","20480") = (100,"48","102-443545","JOHNSON","9","416-82-6316",...
SQLFreeStmt("2007","0") = (0)
SQLFreeStmt("2007","0") = (0)
SQLDisconnect("1010") = (0)
2. Output to File
Command:
>D FILE^SQL0SVR("[FILE NAME]")
Example:
>D FILE^SQL0SVR("c:\temp\svrtrace.log")
Description: This command is used to capture the output from a client/KB_SQL Server
interaction for analysis, debugging, or submittal to KBS Technical Support.
3. Output to Printer
Command:
>OPEN %DEV USE %DEV DO ^SQL0SVR CLOSE %DEV
Example:
>O 3 U 3 D ^SQL0SVR C 3
Description: This command is used to capture output from a client/KB_SQL Server
interaction for analysis, debugging, or submittal to KBSs Technical Support.
4. Without Error Trapping
Command:
DO NOTRAP^SQL0SVR
Description: This option turns off KB_SQL error trapping. When a hard M error is
20
encountered, the server will stop and the error will be displayed in the native format for
your M implementation
Note: The foreground server options are intended only for analysis or debugging
purposes. As it allows only a single connection, it is not appropriate for a multi-user
environment. Background
If you have answered Yes to Allow Connections? in Site Edit/Server Info and your
KB_SQL Server is properly configured, you may start the server simply by logging into
KB_SQL as a DBA or System Manager. You may also type:
>D START^SQL0SVR
at the M prompt. This command line option allows you to start KB_SQL Server during
the startup of your M system or other times without the requirement to log into KB_SQL.
If, for some reason, the Server fails to start, the variable SQLERR may be trapped and be
used to determine the reason for failure.
Stopping the Server
Stopping the Server
You may need to stop the KB_SQL Server for various reasons (shutting down M, system
maintenance, etc.) You may stop the KB_SQL Server with the following command:
D STOP^SQL0SVR
This command may be called from procedures such as Shutdown, etc.
Note: It is important to understand that this command does not affect current connections
to the KB_SQL Server. It does, however, prevent any new connections from being
established. As some applications require multiple database connections for operation, it
is best to ensure that everyone is logged off before stopping the KB_SQL Server. You may
check current connection status by choosing Connections on the System Status menu.

Simulating ODBC with QUICK^SQL
Using QUICK^SQL
The Quick SQL Editor (QUICK^SQL) is a KB_SQL query interface that lets you use
Windows Notepad to enter your SQL statements, save the statements as a text file, and
execute the file from the QUICK utility. Queries executed from this interface take the
same path as a query created from an ODBC application. Because of this you can use this
editor to simulate queries from ODBC applications. The Quick SQL Editor is also a
valuable tool for testing stored procedures and parameterized queries.

Managing ODBC Data Sources
Data Sources
Data Source Types
There are two types of data sources: machine data sources and file data sources. Although
both contain similar information about the source of the data, they differ in the way this
information is stored. Because of these differences, they are used in somewhat different
manners.
Data
Description
source
User
These are local to a computer, and can only be used by the current user. User
DSN
data sources are registered in the HKEY_CURRENT_USER registry subtree.
System These are local to a computer, rather than dedicated to a user. The system, or
DSN
any user having privileges, can use a data source set up with a system data
source. System DSNs are registered in the HKEY_LOCAL_MACHINE
registry subtree.
File
These are file-based sources that can be shared between all users that have the
DSN
same drivers installed, and so have access to the database. These data sources
need not be dedicated to a user or local to a computer. File data sources do not
have a data source name, as user or system data sources do; they are identified
by a file name with a DSN extension.
User and system data sources are collectively known as machine data sources because
they are local to a computer.
Each of these data sources has a tab in the ODBC Administrator that is dedicated to that
type.
File DSN
File data sources are stored in a file and allow connection information to be used
repeatedly by a single user or shared among several users. When a File DSN is used, the
Driver Manager makes the connection to the data source using the information in a .dsn
file. This file can be manipulated like any other file. A File DSN does not have a data
source name, as does a machine data source, and is not registered to any one user or
machine.
A File DSN streamlines the connection process, because the .dsn file contains the
connection string that would otherwise have to be built for a call to the
SQLDriverConnect function. Another advantage of the .dsn file is that it can be copied
to any machine, so that identical data sources can be used by many machines as long as
they have the appropriate driver installed. A File DSN can also be shared by applications.
25
KBSODBCDriver
A shareable File DSN can be placed on a network and used simultaneously by multiple
applications.
A file DSN can also be unshareable. An unshareable .dsn file resides on a single machine
and points to a machine data source. Unshareable File data sources exist mainly to allow
the easy conversion of machine data sources to File DSN so that an application can be
designed to work solely with File DSNs. When the Driver Manager is sent the
information in an unshareable File DSN, it connects as necessary to the machine data
source that the .dsn file points to.
Example
Here is an example of a File DSN for a KB_SQL connection. Note that the file is
typically stored in the default path provided by Microsoft, but the file can be stored
anywhere including on a networked drive.

Tracing ODBC Calls
Tracing API Calls
One of the best ways to understand what is going on when an application uses an ODBC
connection to a remote data source is to trace the conversations. There are several
conversations going on. The client-side-trace refers to the tracing of the conversation
between the application and the ODBC Driver Manager. The server-side-trace refers to
the tracing of the conversation between the KB_SQL ODBC Driver and the KB_SQL
Server.
In general, the server-side trace is the most useful to KBS support and is also the easiest
to interpret.
The client-side trace is a secondary source of information. It can be challenging to
interpret -- let us help you.
Tracing_on_the_Client
Tracing on the Client
The ODBC Driver Manager has a trace facility that allows the sequence of function calls
made by an ODBC application to be recorded and transcribed into a log file. Tracing is
26
performed by a trace DLL that captures calls between the application and the Driver
Manager, and the Driver Manager and the driver. This method of tracing replaces the
tracing performed by the ODBC 2.x Driver Manager and the tracing performed in ODBC
2.x by ODBC Spy.
Enabling tracing
Certain situations call for examination of the conversational exchange between the
application and the driver manager. This can be accomplished using the tracing option
provided by Microsoft.
Sample trace output
The trace file can be large and its contents are not intuitive. However, these details are
invaluable to KBS technical support representatives when trying to diagnose application
27
KBSODBCDriver
behaviors.
Tracing_on_the_Server
Tracing on the Server
In developing your own custom Windows applications for use with your KB_SQL
database, you may find it necessary from time to time to view the interaction between
your application and the KB_SQL Server. All communication between ODBC-compliant
applications and KB_SQL occurs in sequences of function calls. These function calls
may be recorded and reported on for both informative and debugging purposes.
The following sections will describe the enabling of the API Trace feature and the
viewing of the output of an API Trace session.

Interpreting the API Trace
Upon running the SQL_API_SERVER_TRACE query, you will see a screen describing
the connection information for the most recent KB_SQL Server connection. Following
this information is the sequence of function calls from the client application to the
KB_SQL Server, ordered from earliest to last.
There are a number of sources you may use in helping you to determine the functionality
behind each of these function calls:
•
•
•
The online query SQL_API_LIST. This query lists all ODBC API functions
supported by KB_SQL with a brief description of each.
See ServerAPI functions for an overview of the KB_SQL ODBC Architecture as
well as a detailed description of all currently supported function calls.
The Microsoft ODBC 2.0 Programmer’s Reference and SDK Guide. This is the
definitive work on the ODBC specification. KBS recommends this book to
anyone involved in developing and deploying ODBC-compliant applications.
Connection Pooling
Connection pooling
Connection pooling enables an application to use a connection from a pool of established
connections. If a connection has already been created and placed in a pool, an application
can use that connection without performing the entire connection process. Re-using
30
connections from the pool can increase performance since applications can save the
overhead involved in making a connection. This is especially significant for middle-tier
applications that connect over a network or in a situation where the application repeatedly
connects and disconnects (e.g. Internet applications).
Enabling Connection Pooling
Connection pooling can be used by an ODBC application if the application calls
SQLSetEnvAttr with the SQL_ATTR_CONNECTION_POOLING attribute. In order to
enable connection pooling with KB_SQL’s ODBC driver, it will be necessary to enable
the feature and set the timeout value via the ODBC administrator. This timeout value
determines the period of time which an inactive connection is removed from the pool.

Windows Applications
Overview of Windows Applications
Using Windows Applications with KB_SQL is just as it is for using Windows
applications with any other SQL Data Source.
See the documentation for the specific Windows application for more information about
working with SQL Data Sources.
Microsoft Access
Connecting
Connecting from Microsoft Access to your M system is easy using the KB_SQL ODBC
Driver. The connection will be attempted based on a decision made within Access,
typically during the file linking process. You are able to use any of the connection types
and you will be expected to log in with your KB_SQL username and password.
Save password
During the connection process, you will have the option of saving your username and
password with the Access database information. This would allow you to reopen the
database and reconnect to the server without having to reenter your username and
password information. Note also that this capability can be disabled by correctly
configuring the MsysConf table on the server. Contact KB Systems technical support for
more information.
Should I import or link a table?
Microsoft Access provides two choices for using data from an external source:
•
•
Import the M data into a new Microsoft Access table in the current database.
Leave the data in the M database and use it in its current format without importing
it -- this is called linking.
If you know you will use your data only in Microsoft Access, you should import it.
Microsoft Access generally works faster with its own tables, and if you need to, you can
modify the imported table to meet your needs just like any other table created in
Microsoft Access. One of the key considerations here is the volume of data and the
security issues related to removing a copy from the server. These issues should be
considered with your application vendor or information systems department
representative.
If the data you want to use is also being updated by a program other than Microsoft
Access, you should link it. Using this approach, the current methods of updating,
managing, and sharing the data can remain in place, and you can use Microsoft Access to
work with the data as well. For example, you can create queries, forms, and reports that
use the external data, combine external data with the data in Microsoft Access tables, and
even view and edit the external data while others are using it in the original program.
Recordsets: Dynasets and Snapshots
33
KBSODBCDriver
Microsoft Access uses the JET (Joint Exchange Technology) Engine to manage database
interactions. The JET Engine is a powerful query processor with many features, including
the intelligence to perform distributed queries across multiple data sources. The results of
queries run through JET are stored in record sets. These record sets can be of two types:
Dynasets or Snapshots. For the most part, you will probably want snapshots as these are
designed purely for retrieval and reporting purposes. If you are doing updates, dynasets
will allow you to update rows on the remote data source.
Data types
Microsoft Access has its own set of data types. These types are mapped onto the ODBC
types which are themselves mapped on to the data types supported on the data source.
This can lead to confusion. The documentation for Microsoft Access is your best guide to
understanding why the data appears different in an Access database than it does when
you look at the same data on the server.
Microsoft Query
Connecting
Connecting from Microsoft Query to your M system is easy using the KB_SQL ODBC
Driver. As of Microsoft Office97, MSQuery was biased towards the use of file DSNs.
This limitation is removed with Microsoft Office97 Service Pack #2. You are able to use
any of the connection types and you will be expected to log in with your KB_SQL
username and password.
GetExternalData
The option to use MSQuery from Excel and Word is dependent on your installation. The
MSQuery component is not installed by default. If it is not available to you, check with
your system administrator.
Return Data to Excel
Assuming you have the option installed for getting external data, the obvious next step is
to return the data to Excel. The rules for saving the data, query, and password information
are all controlled by the Microsoft applications. Please check with the application
documentation if you have questions about how data is returned.
Data types
Microsoft Query has its own set of data types. These types are mapped onto the ODBC
types which are also mapped to the data types supported on the data source. This can lead
to confusion. The documentation for Microsoft Query, Excel, or Word is your best guide
to understanding why the data appears different in a Microsoft Office application than it
does when you look at the same data on the server.

Programming Considerations
Architecture
Accessing the KB_SQL Engine from Windows
The KB_SQL Client API can be accessed as a dynamic link library (DLL) from
Windows via C or Visual Basic. A Windows programming paradigm, the DLL allows
one copy of a set of functions to be accessed by multiple applications. In Visual Basic,
the Server API is accessed directly through the KB_SQL ODBC Driver. The ODBC
Driver Manager is not involved. Again, TCP/IP provides your connection to the Server
API.
Expectations:
•
Experience with Windows programming, DLLs, Windows applications, and
gateways
Statement Execution
The KB_SQL API supports two methods of statement execution: the direct method
(using the SQLExecDirect function) and the prepare/execute method (using the
SQLPrepare and SQLExecute functions). When an SQL statement is prepared it is sent to
the server, parsed, and optimized. This is the ideal method for statements that are
executed repeatedly, each time with different parameter values.
An application should prepare a statement for execution if any of the following are true:
•
•
The application will repeatedly execute the statement.
The application needs information about the result set before executing the
statement.
An application can execute a statement directly if both are true:
•
•
The application will execute the statement only once.
The application does not need information about the result set before executing
the statement
Parameters
An application can send parameters at statement execution time by calling the following
functions:
SQLBindParameter specifies the SQL data type of the parameters and reserves storage
location for each parameter.
SQLPutData sends data value for the parameter to the driver.
35
KBSODBCDriver
Using data-at-execution parameters is useful for applications handling long data.
See also Parameter_Markers
Parameter Markers
Parameter markers in a prepared SQL statement are placeholders for parameter values
that are supplied by an application. Parameter markers are delimited by question marks.
Using parameter markers in an SQL statement lets you execute the statement repeatedly
with different values. This is a more efficient alternative to coding literal values in an
application, and changing the application each time the parameters change.
To use parameter markers, the application must first call the SQLBindParameter function
to bind a storage area to a parameter marker. Then the application must place the
parameter’s value in the storage location. Examples of using parameter markers are found
in the Stored Procedures section of this chapter.
See also Parameters
Stored Procedures
The KB_SQL Server API supports the use of stored procedures as a collection of
precompiled SQL statements residing on the server. An application can call a procedure
in place of an SQL statement. Stored procedures help to increase performance and
consistency when performing repetitive tasks because they are compiled the first time
they are executed. When executed again, subsequent run time is much shorter than for the
equivalent set of stand-alone statements.
Stored procedures simplify application development because you can repeatedly change
them without modifying and compiling the application.
Stored procedures can be created for permanent or temporary use.
Temporary Stored Procedures
KB_SQL creates a stored procedure for every set of SQL statements that are submitted
from client applications. These procedures are available for use by all server queries for
as long as the procedure is in the buffer of stored queries on the server.
The query text is stored under a name like @SERVER_nnn, where nnn represents the
number of the query relative to the number of stored queries allowed.
IMPORTANT: DBA users can copy the definition of a server query into a new
query, but server queries should not be modified in any way.
Permanent Stored Procedures
KB_SQL can make any stored procedure permanent so that it will always be available
regardless of the size of the stored query buffer. This type of procedure is desirable for
use within custom applications. It allows the application to be developed independently
of the server-side SQL statements. Only the calling parameters and result set must stay
constant. Otherwise, the stored procedure can be modified as needed without affecting
the client application.
Steps to create a permanent stored procedure
1. Create a query that returns a result set in the ODBC format.
SET CLIENT=ODBC
36
This parameter is automatically inserted into SQL statement buffers sent from client
applications. Setting STORED_PROCEDURE implicitly sets the CLIENT type.
2. Indicate that the procedure is permanent.
SET STORED_PROCEDURE=YES
This makes the query take on the characteristics of a stored procedure until you remove
the setting. This query will appear in the result set for the SQLProcedures function.
3. Give names to input parameters (optional).
SET PARAMETERS='name,city,state'
You can choose to specify names for parameter markers in any query.
This acts as documentation, and is accessible in the result of the SQLProcedureColumns
function. Note that setting PARAMETERS implicitly sets the CLIENT type and
STORED_PROCEDURE indicators.
Running a stored procedure
Replace the SQL statements in your application with the ODBC escape clause syntax for
calling a stored procedure.
Syntax
{call procedure-name[(parameter[,parameter...])]}
Example
Replace:
Select Name, Position, Salary, Comments
From Employees
Where EmpDept = ?
With:
{call DeptEmps(?)}
The ‘?’ represents a parameter marker, in this case used to receive the department
identifier.
Rules
•
•
•
•
Users must have SELECT privileges on the stored procedure query.
The stored procedure query must be compiled in order to show in
SQLProcedures, SQLProcedureColumns, or to be executed.
The server will require that the number of parameters in the reference must match
the number in the procedure definition.
Parameter values can be specified as all literals, or all parameter markers, but not
a mix. For example:
Legal
{call xyzProc(?,?)}
{call xyzProc('abc','123')
Illegal
{call xyzProc(?)} -- 2 parameters required
{call xyzProc('abc',?)} -- Cannot mix types
37
KBSODBCDriver
•
If the parameters or the result set changes, you would have to respecify your
application. Otherwise, changes can be made to the logic on the server side by
editing and recompiling the query.
Testing stored procedures
You may test stored procedures by using the sample routine SQLJ13. This program will
let you enter the ODBC syntax for calling the procedure.
Example
>{call xyzProc(?,?)}
>go
Use the Execute SQL option in MSQuery to invoke a stored procedure. Note that this
interface does not have a mechanism for collecting input parameters, so you must supply
the values as string
literals.
Example
{call xyzProc('abc','123')}

Add SQL access to your M routines.
KB_SQL provides SQL access to M data. You can choose to leverage this power for
reporting, data browsing, updating, or any combination. With the KB_SQL API
functions, you can encapsulate your SQL references in your M programs. This
combination allows you to leverage your M programming skills with a well-defined,
controlled interface to the data using SQL.
A Word about Variable Names.
Variable names shown in the following functions are used for illustrative purposes only.
KB_SQL reserves the letters “SQL” for use as the first three letters of our variable
names. We suggest you use variable name conventions suitable to your operation.
KBSStatement
Inserts part of an SQL command into the SQL input buffer.

Notes
•
•
This function can be used to insert partial SQL commands to the SQL server. Its
purpose is to support SQLPrepare.
Splits should occur on a space or punctuation character. A special subroutine,
SPLIT^SQLK4, may be invoked to automate this process
For example, suppose X contains a long line (375 characters), thus exceeding the default
limitation of 255 bytes M imposes on strings.
X SELECT COL1, COL2, COL3, COL4, COL5, COL6,
COL7, COL8, COL9, COL10, COL11, COL12, COL13, COL14,
COL39, COL40 FROM TABLE WHERE COL1 = 100 AND (COL2 = 200)
ORDER BY COL3
You can invoke the SPLIT^SQLK4 subroutine to decompose the line into smaller
segments. It attempts to split first on a space boundary, followed by one of several
punctuation characters.
>D SPLIT^SQLK4
X(0) 7
X(1) SELECT COL1, COL2, COL3, COL4, COL5, COL6, COL7,
X(2) COL8, COL9, COL10, COL11, COL12, COL13, COL14,
X(6) COL36, COL37, COL38, COL39, COL40 FROM TABLE WHERE
X(7) COL1 = 100 AND (COL2 = 200) ORDER BY COL3
Now, you simply call KBSStatement for each entry in X(n).
When using this function, you must still invoke the SQLPrepare function. Typically,
this invocation occurs in the last segment of the SQL command text.
For example, assume X is very long. Below you see a sequence of typical statements
from the subroutine’s point of entry through the call to SQLPrepare.
>D SPLIT^SQLK4
>S N=X(0)
Note: X(0) contains the count of elements.
>F I=1:1:N-1 DO
> . SQLCODE=$$KS^SQLOS(SQLHSTMT,X(I)) I SQLCODE'=0 G Error
>S SQLCODE=$$P^SQLOS(SQLHSTMT,X(N))
Note: If you perform your own split logic, make sure you adhere to all of the rules
observed by the SPLIT^SQLKI subroutine.

Syntax
S SQLCODE=$$FK^SQLOS(SQLHSTMT,PKQUAL,PKOWNER,PKTABLE,
FKQUAL,FKOWNER,FKTABLE)
Notes
•
If PkTableName contains a table name, SQLForeignKeys returns a result set
containing the primary key of the specified table and all of the foreign keys that
refer to it. The result set is ordered by PKTABLE_QUALIFIER,
PKTABLE_OWNER, PKTABLE_NAME, and KEY_SEQ.
Example: To obtain a list of foreign keys that refer to the PATIENT table.
S SQLCODE=$$FK^SQLOS(SQLHSTMT,””,””,”PATIENT”,””,””,””)
•
If FkTableName contains a table name, SQLForeignKeys returns a result set
containing all of the foreign keys in the specified table and the primary keys (in
other tables) to which they refer. The result set is ordered by
FKTABLE_QUALIFIER, FKTABLE_OWNER, FKTABLE_NAME, and
KEY_SEQ.
Example: To obtain a list of foreign keys stored in the PATIENT table.
S SQLCODE=$$FK^SQLOS(SQLHSTMT,””,””,””,””,””,”PATIENT”)
•
If both PkTableName and FkTableName contain table names, SQLForeignKeys
returns the foreign keys in the table specified in FkTableName that refer to the
primary key of the table specified in PkTableName.
Example: To obtain a list of the one foreign key that joins the PATIENT and VISIT
tables.
S SQLCODE=$$FK^SQLOS(SQLHSTMT,””,””,”PATIENT”,””,””,”VISIT”)

A returned value is always a simple string of numbers or characters.
A bitmask requires special handling. Two subroutines, UNMASK ^SQLK4 and
MASK^SQLK4, are provided to assist in this process.
For example, suppose you receive a BitMask value of 1431655765. The following code
demonstrates the effect of the two subroutines:
; Convert Number to BitString
S X=65535
D MASK^SQLK4
W X ; Returns "00000000000000001111111111111111"
; Convert BitString to Number

The example produces a result set of information about the SQL_BIT(FLAG)
data type.
If the TYPE variable is zero (0), the result set contains information about all
supported types. Otherwise, the result set is specific to the one type referenced by
the TYPE variable.
Run the on-line query, SQL_API_DATATYPE, to generate a list of supported
data types.

SQLMoreResults
SQLMoreResults determines whether there are more results available on an hstmt
containing SELECT, UPDATE, INSERT, or DELETE statements and, if so, initializes
processing for those results.
Arguments
Syntax
S SQLCODE=$$MR^SQLOS(SQLHSTMT)
57
KBSODBCDriver
Notes
•
•
•
•
•
•
UPDATE, INSERT, and DELETE statements return a count of affected rows. If
any of these statements are batched, submitted with arrays of parameters, or in
procedures, they can return multiple result sets or counts.
If another result set or count is available, SQLMoreResults returns
SQL_SUCCESS and initializes the result set or count for additional processing.
After calling SQLMoreResults for SELECT statements, an application can call
functions to determine the characteristics of the result set and to retrieve data from
the result set. After calling SQLMoreResults for UPDATE, INSERT, or DELETE
statements, an application can call SQLRowCount.
If all results have been processed, SQLMoreResults returns
SQL_NO_DATA_FOUND.
Note that if there is a current result set with unfetched rows, SQLMoreResults
discards that result set and makes the next result set or count available.
If a batch of statements or a procedure mixes other SQL statements with
SELECT, UPDATE, INSERT, and DELETE statements, these other statements
do not affect SQLMoreResults.
SQLNativeSql
SQLNativeSql returns the SQL command text as translated by the server.
Arguments
LinesIn [IN]
ArrayIn [XIN]
LinesOut [OUT]
ArrayOut [XOUT]
Syntax
S SQLCODE=$$NS^SQLOS(SQLHDBC,IN,XIN,.OUT,XOUT)

ActiveX Data Objects (ADO)
Overview of ADO Programming
Programming using ADO with KB_SQL is just as it is for using ADO with any other
SQL Data Source.
See www.microsoft.com/data for more information.
70
Appendixes
A - Escape Sequences
Extensions
SQL Extensions
KB_SQL API supports several ODBC SQL extensions:
•
•
•
•
the representation of date and time literals
the syntax for scalar functions
LIKE predicate escape characters
stored procedures
These extensions provide essential functionality that is shared by most DBMSs.
However, because the syntax required by the DBMSs varies, ODBC uses a syntactical
notation called the escape clause. The escape clause consists of a pair of curly braces {}
which surround the standard SQL syntax form and a token which specifies the type of
clause.
Date, Time, and TimeStamp
Date, Time, and Timestamp Data
KB_SQL API supports the DATE, TIME, and TIMESTAMP (a combined form of DATE
and TIME) data types. The shorthand escape clause syntax for these data types is:
{d 'value'} {d '1999-04-28'}
April 28, 1999
{t 'value'} {t '10:30:00'}
10:30 AM
{ts 'value'} {ts '1999-04-28 10:30:00'} April 28, 1999 at 10:30 AM
Wildcards
Wildcards (Search Pattern Escape Characters)
ODBC supports wildcards using the underscore character (_) for single-character
replacement and the percent sign (%) for multiple-character replacement.
A word of caution is in order with respect to the use of wildcards, particularly in relation
to the various catalog functions where the SQL_IDENTIFIER can include the underscore
character. When you want to use a meta character as a literal and not as a wildcard, you
must precede the meta character with the search pattern escape character (the default is
the backward slash).
71
KBSODBCDriver
For example, to obtain all columns for the LAB_PATIENT table where the underscore is
a literal in the SQL_IDENTIFIER, you send the table name parameter as:
LAB\_PATIENT
Using the escape character prevents the engine from interpreting the underscore as a
wildcard, thus avoiding retrieving columns for tables that could be named LABaTABLE,
LABbTABLE, and so forth.
Scalar functions
Scalar Functions
Scalar (or row) functions operate on a single value. They include functions that compute
absolute value or length, format a date or time, or return a substring. The on-line query
SQL_FUNCTION_LIST provides a complete list of the KB_SQL API scalar functions
and their syntax.

LIKE Predicate Escape Characters
The support of the LIKE predicate escape clause allows for searches to include
metacharacters. In a LIKE predicate, the underscore character (_) is used for singlecharacter replacement and the percent sign (%) is used for multiple-character
replacement. The percent and underscore characters can be used as literals in a LIKE
predicate by preceding them with an escape character.
The escape clause for ODBC queries looks like:
{escape ‘escape-character’}
Example
{escape ‘\’}
Example
Items
aab aac
aad aazz
aa_123 aa_245
abc ade
74
Appendixes
SQL without escape character
select code
from item_master
where code like ‘aa_%’
Returns
aab aac
aad aazz
aa_123 aa_245
SQL with escape character
select code
from item_master
where code like ‘aa\_%’
Returns
aa_123
aa_245
Notes
•
•
•
The default LIKE escape character is '\' (backslash).
The escape character can be specified using the escape clause syntax: {escape '\'}.
The SQL Editor supports the feature, but does not use the {} syntax.

The KB_SQL Server API supports the use of stored procedures as a collection of
precompiled SQL statements residing on the server.
An application can call a procedure in place of an SQL statement.
KB_SQL supports temporary and permanent stored procedures.
A temporary stored procedure is stored in the cache of recent SQL commands on
the server.
A permanent stored procedure is stored as a query definition on the server.
Stored procedures can improve performance by eliminating query compilation at
runtime.
Permanent stored procedures can simplify application development, as most
changes to procedures are isolated on the server.
Procedures can return a result set (1 or more columns, 1 or more rows)
Procedures can perform DML, DCL, and DDL operations, returning no result set.

KBSODBCDriver
Outer Joins
The KB_SQL Outer Join syntax is proprietary to KBS. For generic applications, use of
this syntax would compromise the portability of the application. To avoid this limitation,
generic applications use the ODBC escape clause to encapsulate the outer join syntax,
allowing the specific driver to translate into a native syntax where necessary. This is
exactly what KB_SQL does.
ODBC uses escape sequences for outer joins. The syntax of this escape sequence is as
follows:
{oj outer-join}
where outer-join is:
table-reference {LEFT | RIGHT | FULL} OUTER JOIN {table-reference | outer-join}
ON search-condition
Note that any terms in {braces} indicate that only one of the terms would appear in a
phrase. For example, an outer join would be characterized as one of LEFT, RIGHT, or
FULL.
Note also that the outer-join term can be included as part of the outer-join specification.
Although the nesting of outer joins might be a desired feature, KB_SQL does not
currently support this capability as of 10/18/2001.
B - Connection Options
Connection options
The ODBC interface allows some flexibility in the ways in which a client application can
achieve a connection to a server-based data source. The choice of option is sometimes
left to the application such as the case of Microsoft Office products. Other situations give
the developer the choice of connection strategy. These strategies are basically trading off
of several considerations, including:
•
Control over appearance of dialogs in your application.
If you are building a custom application, you will want to control the dialogs that are
presented to your customers. At a minimum, his translates to using SQLConnect and
NOT using SQLDriverConnect.
•
Whether or not you require a pre-configured data source to define the parameters
of the connection.
If you are building a custom application, you might want total control over the
connection parameters. You can accomplish this by controlling the creation of the data
source. You can also control this by putting the connection parameter value information
in the application code and connecting without a pre-defined data source. See File Data
Sources and DSN-less Connections.
76
Appendixes
•
When using a commercial application, your options are limited to the choices
made by the developers.
Sometimes this means that you are forced to create a certain type of connection and
certain connection strategies are not available. When evaluating a new ODBC-enabled
application, it is valuable to review the connection options that are supported.
SQLConnect
SQLConnect is the simplest connection function. It requires a data source name and
accepts an optional user ID and password. It works well for applications that hard-code a
data source name and do not require a user ID or password. It also works well for
applications that want to control their own “look and feel,” or that have no user interface.
Such applications can build a list of data sources using SQLDataSources; prompt the
user for data source, user ID, and password; and then call SQLConnect.
The SQLConnect function establishes connections to a driver and a data source. The
connection handle references storage of all information about the connection to the data
source, including status, transaction state, and error information.
It requires the following:
•
•
•
A valid connection handle (hdbc).
A valid KB_SQL username.
A valid KB_SQL password.
Connecting from a C program.
/* Connect to data source */
rc = SQLConnect(hdbc, // hdbc is the connection handle
(SQLCHAR*) "Sales", SQL_NTS, // Sales is the DataSourceName
(SQLCHAR*) "DBA", SQL_NTS, // DBA is the username
(SQLCHAR*) "SHARK", SQL_NTS); // SHARK is the password
Connection from a M program.
S rc=$$C^SQLOS("M", "DBA", "SHARK", hdbc)
// M is the DataSourceName
// DBA is the username
// SHARK is the password
// hdbc is the connection handle
See SQLAllocConnect for information on connection handles.
Note that the values of "Sales", "DBA", and "SHARK" are used for illustrative purposes
only.
SQLDriverConnect
SQLDriverConnect is used to connect to a data source using a connection string.
SQLDriverConnect is used instead of SQLConnect for the following reasons:
77
KBSODBCDriver
•
•
•
To let the application use driver-specific connection information.
To request that the driver prompt the user for connection information.
To connect without specifying a data source.
SQLDriverConnect is an alternative to SQLConnect. It supports data sources that
require more connection information than the three arguments in SQLConnect, dialog
boxes to prompt the user for all connection information, and data sources that are not
defined in the system information.
SQLDriverConnect provides the following connection attributes:
•
•
•
•
Establish a connection using a connection string that contains the data source
name, one or more user IDs, one or more passwords, and other information
required by the data source.
Establish a connection using a partial connection string or no additional
information; in this case, the Driver Manager and the driver can each prompt the
user for connection information.
Establish a connection to a data source that is not defined in the system
information. If the application supplies a partial connection string, the driver can
prompt the user for connection information. See DSN-Less Connections.
Establish a connection to a data source using a connection string constructed from
the information in a .dsn file. See File Data Sources.
After a connection is established, SQLDriverConnect returns the completed connection
string. The application can use this string for subsequent connection requests. For more
information, see the Microsoft ODBC documentation.
Note that the SQLDriverConnect function is not available in the M-based interface. For
connections from M programs, use the SQLConnect function.
DSN-less Connections
If you are using ODBC 3.0 and a connection without DSN, or a file DSN, to connect to
your server, you can set the additional connection properties supported by the driver.
Connection Parameters
UID=UserName
PWD=PassWord
Driver=KB_SQL ODBC 32-bit Driver
Host=ServerAddress
TCP_PORT=ServerListeningPort

// DsnLessConnect.cpp
#include "stdafx.h"

C - Error Messages
Message Format
When using the KB_SQL ODBC Driver, you may encounter errors and messages of one
type or another. It is useful to understand the format of the messages so that you can
determine the source of the error or warning. This information is also useful when
reporting errors to KBS for technical support.
Syntax
All messages have the following format:
SQLSTATE (native_error_code);[vendor_name]
79
KBSODBCDriver
[module_name][version_number]API_function; error_message
Description
SQLSTATE codes are a standard naming scheme for errors
SQLSTATE
developed by the SQL Access Group (SAG). The returned native
error code is mapped to the appropriate SQLSTATE code. If the
native error code does not have a corresponding SQLSTATE code,
the KB_SQL ODBC Driver returns SQLSTATE 37000 (Syntax error
or access violation).
Native_error_code The native error code number will be included for any error
generated by the KB_SQL Server API. It corresponds to a KB_SQL
specific error message.
This is the vendor name of the provider of the module that reported
Vendor_name
the error. In the example below, it is KBS, the provider of the Server
API. It could also be Microsoft, if the module was the ODBC Driver
Manager.
This is the module responsible for the error. In the example below, it
Module_name
is the KB_SQL Server API. Errors can also be tagged with KB_SQL
ODBC Driver for errors generated by the driver.
Version_number This is the version number of the module that reported the error. In
the example below, it is version 3.6
This is the name of the API function that was last invoked. This
API_function
name will prefix the first error generated for a particular API
function call.
This is the native error text that corresponds to the native error code.
Error_message
In the example below, the test corresponds to the error code for
#530.
Example
28000 (530): [Knowledge Based Systems, Inc.][Server API][V3.6] SQLConnect: User
name / password failure
Note: For a complete list of all the possible errors and their descriptions, see one of the
following queries: SQL_API_SQLSTATE or SQL_ERROR_LIST.
SQLCODE
Error processing typically handles the following values for SQLCODE. See also, the
SQLError function.

E - Data Types
Data Type Mapping
The KB_SQL Server driver maps Server datatypes to ODBC SQL datatypes. The
following table lists all Server datatypes and shows the ODBC SQL datatypes to which
they are mapped. Note that multiple Server types can map to a single ODBC type, but
each ODBC type maps to only one Server type.

It is valuable to recognize the type names and numbers in both contexts. Working with
ServerAPI queries, either using the host-based interface or through ODBC queries, you
will see the ODBC SQLType values going back and forth.
Data Type Formats
Information is exchanged between the client application and the ODBC Driver using data
formats as defined in the C programming language. The exchange of data between the
driver and server is primarily done using character string representations of the data, with
conversions applied on either side as necessary.
It is important to realize that certain data that might appear as numbers to us in M terms
might not be a number at all in terms of a non-M application.
For example, the DATE, TIME, and MOMENT types are exchanged between the server
and driver as character strings in a particular format defined by ODBC. See the table
91
KBSODBCDriver
below. These values are stored in the driver in a structure and provided to the application
in an application-defined format. It is important to understand that the display formatting
of the data is the responsible of the application.
Consider also the FLAG data type. Using the SQL Editor, you might be used to thinking
of FLAG types as YES/NO or TRUE/FALSE. In the exchange between the driver and
server, these values are represented as 1 (true), 0 (false), or NULL if unknown.
Depending on the application, you could see flag values displayed as -1, Yes/No, or
almost any other format applicable to a binary choice.
Character strings deserve special consideration as well. In C, a character string can be
referenced using several strategies based on the storage of character strings as a array of
character bytes. Some applications use a null-terminated-string approach, allowing
character strings to be of arbitrary length as long as they are null-terminated. Other
applications will use the defined length, as retrieved from SQLDescribeCol, to reference
the value as a fixed-length string. This can lead to errors if the actual lengths of your data
exceeds the defined length. In these cases, the driver is responsible to raise a warning
message about the truncation of the data value. The handling of this warning message is
application-dependent. There is a server-side utility, named SQLJ14, that can be used to
find data values that exceed the defined length in the data dictionary. Contact KBS
technical support if you need assistance with this important issue.
For the most part, data of the TEXT type appears to the ODBC driver as a character
string. It just happens to allow a larger maximum size. On the server side, the TEXT data
is stored in a global array of subscripted segments of character strings. The only
important point to realize is that the data has no inherent formatting. It is simply a stream
of bytes. As with the other types, the application is in control of the formatting.
See Data Type Mapping for information about how KB_SQL data types are mapped to
the ODBC types.

ODBC format values going back and forth.
