Ah, there is a way to write it so that you can have at most one of those constraints where only one makes sense, and not require a specific order of constraints, but it'd require listing all the possible orderings, which would be impractical. So if one wanted to enforce that there's at most one of such constraints then the best pace to do it in in sqlite3AddDefaultValue() and friends, rather than in the grammar. But really, is it worth it? _______________________________________________ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users
