It would make an interesting OT thread, if you're inclined to start it. ;-) I've always thought user-defined types were unnecessary except as a convenience. There are few new primitive types; most user-defined types I can think of are "structures" -- sets of columns -- that one might like to name and constrain as a new type that may appear in many tables. About the only primitive type I can imagine are mathematical: complex numbers or exact numeric representations. --jkl _______________________________________________ sqlite-users mailing list [email protected] http://mailinglists.sqlite.org/cgi-bin/mailman/listinfo/sqlite-users
