Pointing out the implication that a maximum table size necessarily limits the maximumnumber of rows stored benefits a very small fraction of the audience but it doesn't cause any harm to the remainderand doesn't cost much to implement. You could also provide a range: 20 to millions+; based on the max row size of 1.2TB and whatever the minimum size would result in. David J.
