>No, _TALLY holds the # of records returned by SQL Select not the # of found records.
>A query with agregate function and w/o GRPUP BY returns one record IN VFP9 regardless if there were any matching records. It's ANSI SQL behavior. You have to use ISNULL() function to see if any matching records have been found.

Thank you for the explanation.
