have been wondering for quite a while
DBAs: On the user_constraints view, you can find the constraint_type has five distinct values: C, O, P, R, U, and V. C=check, P=primary key, R=foreign key, U=unique key. What about O and V? If I assume O=optional(null/not null), I really can not guess V. Anyone can help?, Thanks in advance.
