For an analogous situation in SQL I would propose select (select foo from bar where xyz); if there are no records in bar it returns NULL. Only if there are multiple records in bar or some sort of error in the subquery does it produce an error. Does SQL-99 not say anything about this case? It seems like the kind of thing a standard should specify. -- greg ---------------------------(end of broadcast)--------------------------- TIP 8: explain analyze is your friend
