[unixODBC-support] problems with 64 bit SQLBindParameter()

Thanks for your response.

But unfortunately, my application is setting up two ODBC connections to two
different DB at the same time, one is postgresql, 
the other is TimesTen.

For TimesTen, it has to be be REAL 64 bit mode (when I tried with non REAL
64 bit mode, core dump occured), for Postgresql, 
SQLBindParameter() can not work if REAL 64 bit mode. Seems what's the
handling of two drivers are totally different.

Could you pls have some recommendations how to figure it out.

You don't need the REAL 64 bit mode, especially if the driver doesn't
understand. Thats why its not the default.

Try as normal, and it should be fine.
