(oracle 12c) 使用 new.column 触发时出现 pls-00201 错误

Question

我想触发 emp.sal < 10 时引发错误。

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
  WHEN sal_lease_than_ten_error THEN
  RAISE_APPLICATION_ERROR(-20001, 'give me more');
END;
/

如何比较新的emp.sal 和10？
