Because the following UPDATE request specifies the correlation name e for employee in its FROM clause, you must specify e in place of employee immediately following the UPDATE keyword.

     UPDATE e
     FROM employee AS e, department AS d
     SET salary = salary * 1.05
     WHERE e.emp_no = d.emp_no;
