Please remember there's always an ODBC driver manager
between your app and the ODBC driver. Though your app
calls many ODBC 3.0 specific APIs, the driver manager
translates them into ODBC 2.50 APIs as much as possible
when you are using ODBC 2.50 driver via your DSN definition.
My trial ODBC 3.0 driver implements many(? at least not all
unfortunately) of ODBC 3.0 specific APIs and the driver
manager doesn't have to translate them.
