You're on the right track, but there's no need to do a SELECT first. Do an UPDATE SET number=number+1, and check the returned number of modified rows. If it returns 0, do the INSERT. -- Cory Nelson http://int64.org _______________________________________________ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users
