Hitchhiker's Guide to VBSQL -- VBSQL vs ODBC API Data Access

ID: Q111490

The information in this article applies to:

Microsoft Visual Basic Professional Edition for Windows, version 3.0

SUMMARY

If you want to use ODBC API functions instead of VBSQL data object variables for data access in Visual Basic, consider the following issues:

On average, the data access speed of the VBSQL API functions versus ODBC API functions is about equal. ODBC does some calls slightly faster, and VBSQL (DBLIB) does some other calls faster.

The VBSQL API may be slightly easier to use than the ODBC API, but is not as generic as the ODBC API.

If portability to C is important to you, the API calls for VBSQL are identical to the C calls -- except with C you need to bind each variable with each column, which can be tedious. The error handlers with VBSQL resemble the C language in that VBSQL implements real call-back handlers, but this is not an option with the ODBC API.

MORE INFORMATION

The VBSQL.VBX custom control file comes from the Microsoft SQL Server Programmer's Toolkit for Visual Basic.

The following guide offers further information on VBSQL:

The Third Edition covers accessing the SQL Server (Microsoft and Sybase) through VBSQL (DBLIB) and data access object variables in Visual Basic version 3.0. This is a definitive work on accessing the SQL Server from Visual Basic.

Open Database Connectivity (ODBC)

The greatest impact of Open Database Connectivity (ODBC) is on organizations where information is stored on a variety of dissimilar computers and databases. Under the ODBC scheme, a driver written for a specific database program, such as ORACLE, Ingres, or IBMs DB2, acts as the intermediary between the application and the database.

By using ODBC calls and the appropriate driver(s), the same application, be it a spreadsheet or an accounting package, can easily extract and manipulate information stored in a variety of databases.

ODBC-compliant applications include Microsoft Excel version 5.0 and Word version 6.0.
