  AND d.dep_location IN ('SYDNEY',
                         'PERTH')
  AND e.salary BETWEEN s.min_sal AND s.max_sal

          FROM employees e,
               salary_grade s
          WHERE e.salary BETWEEN s.min_sal AND s.max_sal
            AND e.emp_name = 'TUCKER')

          FROM employees
          WHERE emp_name = 'SANDRINE')) ;
