This example shows how the DELETE and SELECT constraints are applied when a user without the required OVERRIDE privileges attempts to execute a DELETE statement on a table that has the row-level security DELETE and SELECT constraints.

An EXPLAIN request modifier is used to show the steps involved in the execution of the request and the outcome of the application of the constraints.

The statement used to create the table in this example is:

     CREATE TABLE rls_tbl(
       col1 INT,
       col2 INT, 
       classification_levels   CONSTRAINT,
       classification_categories CONSTRAINT);

The user’s session constraint values are:

     Constraint1Name LEVELS
     Constraint1Value 2
     Constraint3Name CATEGORIES
     Constraint3Value '90000000'xb
