This error is returned in three cases:
* The name of the triggering table or the synonym, if it is used, matches the old or new correlation name in the REFERENCING clause.
* The name of a table or a synonym that is referenced in the action clause matches either the old or new correlation name in the REFERENCING clause.
* The old correlation name matches the new correlation name.
Change either the correlation name or the table name, and execute the CREATE TRIGGER statement again.
