Question

I’m receiving an error that I can’t make sense of. The error is pretty straightforward:

ORA-00001: unique constraint (*schema*.*xyz_constraint*) violated

However, what’s causing my confusion is the fact that no such constraint seems to exist. It’s certainly not defined on the table; the DB in question has almost no referential integrity defined, and the particular table into which I’m inserting data has no key defined.

For what it’s worth, I can’t find the constraint anywhere in the database:

    select *
    from all_constraints 
    where constraint_name like '%xyz_constraint%'

Is there anything I’m overlooking? Thanks.

Answer 1

This happens when the constraint belongs to another user and you don’t have permissions to it.

Try looking it once again for now from SYS perspective
