Hello, I have been attempting to place primary and foreign key constraints on an existing database, and have seen something in the SYSCONSTRAINTS table that I can't account for. The manual being the most user friendly of references (sic) does not mention a CONSTRTYPE of "N", yet I see these types entered in this table. Can someone explain what this type is and how it gets defined. Regards
