You declared that the primary key is only on the field (ID). There are no other fields involved. You also declared that the engine should create and maintain a separate index on the field (field2). There are no contstraints built into a "regular" index. Does that help? Shawn Green Database Administrator Unimin Corporation - Spruce Pine
