An informational constraints is not enforced in INSERTs and UPDATEs. This means you can insert data which violates your informational constraint. However, it also means you will not see this data in a SELECT. Is there anyway you can see the data without removing constraint.

Cheers.

What did you mean by "this data"?
I thought that I can see any data in a table, if it was not gurded by some security functions.
Can you show an example?

I think he/she wants a report of data which is inconsistent according to the informational contraints. Kind of a "set integrity" in pro-deo mode

Not possible as far a I know. Not too hard to code in SQL yourself.
