One problem here is that COUNT(*) is CARDINALITY of the set qua set, while COUNT([DISTINCT] <exp>) is at the element level inside the set. Maybe we should have made the syntax: "CARDINALITY(<table expression>)" so you'd know the level that the operatgor is working at. Received on Mon Jun 14 2004 - 22:57:05 CDT
