Mysql 在多个触发器中使用存储过程

除了notes表之外，我还将这个触发器应用于大约15个其他表。不确定，但似乎存储过程将消除重复的代码。这是一个很好的存储过程应用程序吗？如果是，如何实施

CREATE TRIGGER tg_notes_ins BEFORE INSERT ON notes FOR EACH ROW
BEGIN
    IF NEW.created_by_user IS NULL OR NEW.created_by_user = '' THEN
        SET NEW.created_by_user = @users_id;
    END IF;
    IF NEW.modified_by_user IS NULL OR NEW.modified_by_user = '' THEN
        SET NEW.modified_by_user = @users_id;
    END IF;
END$$

CREATE TRIGGER tg_notes_upd BEFORE UPDATE ON notes FOR EACH ROW
BEGIN
    IF NEW.modified_by_user = OLD.modified_by_user THEN
        SET NEW.modified_by_user = @users_id;
    END IF;
END$$

我不是说这是怎么做的，但它似乎是工作，并将感谢任何意见。谢谢

    END IF;
    IF NEW.modified_by_user IS NULL OR NEW.modified_by_user = '' THEN
        SET NEW.modified_by_user = @users_id;

        SET NEW.modified_by_user = @users_id;
    END IF;
END$$

    CALL createRecord();
END$$
