Several possible uses exist for using a SET SESSION CONSTRAINT request to alter the row-level security constraints in effect for the session. The noted changes can be applied whether the default row-level security constraint set for the session was assigned to a user or to a profile. The following points indicate some of the possible uses for a SET SESSION CONSTRAINT request.

  • To change the default level (hierarchical) constraint for a session.
  • To change the active category (non-hierarchical) constraint set for a session to a subset of those defined for the constraint.
