thank you, of course that is right. It was not my idea but the
strategy behind IBObjects Recordcount method for this query. I was
analyzing it because of the unexpected result.

But how can I determine the number of record after grouping? Fetching
all in a while loop? As I often recognize, SQL is so easy in the books
but not so easy, when solving real worlds queries. ;-)
