If the recordsource of the grid is a buffered table, then you will also need to include the "WITH (BUFFERING = lExpr)" optional clause or make sure that Set SQLBuffering ON.

I'm also guessing that you can't use it because you have a RecordSource that has data, but also has a filter applied and you need to determine when no data meets the filter requirements. If all of that is the case, then you could do something like this:

>lcFilter = SET('Filter')

>  WHERE &lcFilter
>
>RETURN (NVL(laCount[1], 0) > 0)
>
>Make that a function and it will return .t. if the current RecordSource contains any rows that meet the current filter condition.
