I have come across a situation where I think I need both a check--
constraint and a referential constraint on the same column to handle
different situations.
When a row is inserted the default value for the status column will be 'N'.
When the information has been validated it will change to 'V'. This
is my current check constraint.
If the validation is overridden an override code can be placed into
the status column from an exception table. This is my referential constraint.
I have thought about adding the check values to the exception table
and excluding them from the exception prompt but I would prefer to
handle it without doing that if possible. If I can't have both
constraints on the status column this is probably what I will do.
