Low Level Table Open Techniques

Every database driver includes a package that contains definitions and commands specific to that environment:

• MSSQLdrv.pkg for SQL Server
• DB2_drv.pkg for DB2
• ODBC_drv.pkg for ODBC
• DFBTRdrv.pkg for Pervasive.SQL

You can use these in DataFlex source code to make your application more back-end specific. This might make the program unusable for other database types.

In addition to the commands defined in the driver package, you can use Embedded SQL.
