In the Win32 environment, the ODBC 3.x driver manager is required to use the ODBC 3.51 driver. This version of the driver manager automatically supports both 3.x applications and older, pre-3.x applications. Calls to deprecated APIs by older applications are automatically re-mapped to the 3.x APIs.
