rls_constraint_name
Name of one or more row-level security constraints, each followed by a list of the hierarchical levels or non-hierarchical categories, valid for the constraint, which are being assigned to the profile_name.
For more information about row-level security constraints, see CREATE CONSTRAINT.
level_name
List of the hierarchical levels. Example level (hierarchical) constraint assignment:
CONSTRAINT = Classification_Level (Secret, Unclassified DEFAULT)
category_name
List of non-hierarchical categories. Example category (non-hierarchical) constraint assignment:
CONSTRAINT = Classification_Country (US, UK, GER)
There is a limit of 6 hierarchical constraints and 2 non-hierarchical constraints that can be assigned per profile.
DEFAULT
DEFAULT can be specified for 1 classification level from the specified list of levels for a hierarchical constraint. The specified level becomes the default value for the constraint when a session is established for the user to which the profile is assigned.
If you do not specify DEFAULT for any of the listed classification levels, then the first level listed becomes the default for the profile.
DEFAULT is not valid for non-hierarchical constraints.
