Home -> Community -> Usenet -> comp.databases.theory -> Re: Counting propositions
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.
