By default, row inserts into RLS-protected tables done by users with OVERRIDE privileges require values to be specified for the constraint columns. This prevents these users from doing bulk loads through client loaders because data is read from external files.
The system can be configured to allow a user with OVERRIDE privileges and non-null session constraints to perform simple and bulk inserts without explicitly specifying constraint values for the constraint columns.
To enable this functionality, contact the Teradata Support Center.
