If you have the required security credentials to read all rows in the table or have override select constraint privileges on the table, this statement returns emp_name and group_membership row-level security constraint value name and value code for all managers. If you do not have the required credentials or override privileges on the table, no rows are returned.

You cannot specify a row-level security constraint value name as the WHERE clause search condition. You must specify a value code. In this example, the value code 90 represents the value name manager.

     SELECT emp_name, group_membership
     FROM emp_record
     WHERE group_membership=90;
