Help with sql identifying dup constraints

Barbara Baker

Hi, all.
I appear to have a bit of a mess on my hands. I've
identified some tables that have a duplicate "not
null" constraint on the same column. Only difference
in the constraints is that one is generated and one is
user named (even tho they're both sys_c00xxx
constraints).

(I believe this happened when a vendor used a 3rd
party pkg to try to duplicate their schema in our
database.)

I'd like to identify all of the tables with this
condition. Any method I can think to do this requires
comparing the search condition of dba_constraints,
which is a LONG.

Can anyone think of a way to do this? Perhaps I'm
overlooking something simple. Thanks for any help.
