I understand. This is completly non neural problem. But for business aplications it is very important question. select count(*) or select count (field)
I think that SQL implementation is well. count (*) returns 3 and count (field) should return 2. But, as I said before, I dont support declarative queries, so this question is completly open and should be resolved by developer, as he wish. Received on Thu Jul 06 2006 - 11:02:09 CDT
