Each CONSTRAINT object defines a set of row level security constraints, including:

  • A security label category and the range of values (levels or compartments) for the category.
  • Specification of up to 4 UDFs, INSERT, SELECT, UPDATE and DELETE, which define and enforce the security constraints.

You can apply the security constraints in a CONSTRAINT object to a:

  • User, by specifying the CONSTRAINT object in a:
    • CREATE USER or MODIFY USER statement
    • CREATE PROFILE or MODIFY PROFILE statement, and then assigning the profile to the user
  • Table, by defining a constraint column that is named for the CONSTRAINT object in a CREATE TABLE or ALTER TABLE statement.
