The postgres backend can't handle parameters like this.  But, the odbc driver
can.  If you create your sql with the parameter markers (?) and then use
SQLBindParameter to supply the parameter values.  The driver then replaces the
parameter markers with your parameter data.  Access and others do this all the
time and it works great!

Now, as far as VB goes, I'm not sure how SQLBindParameter translates.

Hope this helps.
