I want to make trigger this is raising error when emp.sal < 10 .

CREATE OR REPLACE TRIGGER sal_more_than_ten_trigger
  BEFORE INSERT OR UPDATE ON emp FOR EACH ROW
  DECLARE
  sal_lease_than_ten_error EXCEPTION;
  BEGIN
    IF new.sal < 10 THEN -- error occured!!!!!!!!!!!!!!!!!!!!!!!!!
      RAISE sal_lease_than_ten_error;
    END IF;
  EXCEPTION
