Thanks and okay, I can accept that such a set can be recorded. Not trying to distort that answer since I think you have already expressed some lack of absolute certainty about RVA's "making any sense", but I think that if that set is empty, I don't even need an RVA to satisfy the requirement, all I need to do is define a table/relvar and go home, courtesy of the closed-world-assumption. If I were using my foolhardy (likely) dream system that raised no exceptions, I wouldn't even need to do that and could write my invoice on the spot! Received on Fri Nov 02 2007 - 01:22:52 CET
