select max(salary) into v_maxsal from employees;
select min(salary) into v_minsal from employees;
select salary into v_sal from employees where employee_id=201;
update employees set salary=salary+8000 where employee_id=201;
if v_sal>v_maxsal then raise e_highlimit;
elsif v_sal<v_minsal then raise e_highlimit;
end if;
exception
when e_highlimit then
