"http://www.sqlite.org/foreignkeys.html#fk_enable seems to suggest that "PRAGMA foreign_keys = ON" never returns anything, and it's only "PRAGMA foreign_keys" which returns 0, 1 or None (when unsupported)." That was it, exactly, Rob. I don't know where I got the idea that I was getting a '1' from the 'ON' command, although I was sure that I'd seen it. But once I just called "foreign_key" it returned just fine. Ummm... Obviously I was up fiddling around too late. Yeah, that's it. Thanks!
