This example deletes rows from the employee table for managers who have less work experience than their employees. This delete performs a self-join on the employee table:

     DELETE FROM employee AS managers
     WHERE managers.deptno = employee.deptno
     AND   managers.jobtitle IN ('Manager', 'Vice Pres')
     AND   employee.yrsexp > managers.yrsexp;
