'AS' clause doesn't required in this case but it doesn't hurt either.

>Second... SQL Passthrough to either Oracle, SQL or whatever has NO idea of the "?Thisform." parameterizing parts. So... prebuild a local var for these respective values and add into the SQL-Passthrough call where needed.

Oracle or SQL wouldn't see '?' parameters because they are processed by SQLEXEC() and converted into a form that ODBC/backend can understand.
