mysql – 创建触发器错误：语法无效

SQL查询：

CREATE TRIGGER tg_newuser_insert
BEFORE INSERT ON tbl_newuser
FOR EACH ROW
BEGIN
  INSERT INTO tbl_seq VALUES (NULL)
  SET NEW.id = CONCAT('YTUM', LPAD(LAST_INSERT_ID(), 8, '00000'));
END

MySQL said: Documentation
#1064 – You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ‘SET NEW.id = CONCAT(‘YTUM’, LPAD(LAST_INSERT_ID(), 8, ‘00000’));
END’ at line 6

解决方法:

您的格式设置已关闭,请记住DELIMITER $$语句是必需的,因为它与创建存储过程没有什么不同.

Check the documentation any time you run into issues like this.

滚动文档大约一半以查看示例.

但是,这就是你要找的东西：

DELIMITER $$
CREATE TRIGGER tg_newuser_insert 
BEFORE UPDATE ON tbl_newuser
FOR EACH ROW
    BEGIN

        SET NEW.id = CONCAT('YTUM', LPAD(LAST_INSERT_ID(), 8, '00000'));

    END $$
DELIMITER ;
