I think Nathan's point is that the integer you get when declaring a column INTEGER PRIMARY KEY can hold a 64-bit value anyway, so why couldn't it simply be declared differently and behave the same?
Personally I think this is an application problem, but I thought his point was valid and I'm thus curious myself. -T On Mon, Dec 15, 2008 at 10:58 AM, D.
