There are two ways that you can obtain ODBC drivers for use with PowerBuilder:
From Sybase (recommended) Install one or more of the ODBC drivers shipped with PowerBuilder. You can do this when you first install PowerBuilder, or later.
From another vendor PowerBuilder Enterprise and PowerBuilder Professional let you access data with any Level 1 or higher ODBC-compliant drivers obtained from a vendor other than Sybase. In most cases, these drivers will work with PowerBuilder.
