I think you have to set the environment attribute, whether
you want to do ODBC-Ver 2 or 3. Furthermore it is a good idea
to check the return code after the allocation calls.

sqlucode.h. The ODBC driver contains both, ASCII and Unicode functions.
In case of Windows, always the Unicode API is used. If the application
is non Unicode, the driver manager maps the calls (see ODBC reference).
