2、错误原因

DELIMITER $$

CREATE
    /*[DEFINER = { user | CURRENT_USER }]*/
    TRIGGER `test`.`insert_data` BEFORE INSERT
    ON `test`.`emp`
    FOR EACH ROW BEGIN
	INSERT INTO t_depart_info(id,depart_name,depart_teacher) VALUES(3,'you','zhangsan');
    END$$

DELIMITER ;

INSERT INTO emp VALUES(6,'胡迪',20,'男');

触发器中插入的第三个记录的数据类型是int，但是插入的是varchar类型，导致报错

3、解决办法

（1）将t_depart_info表中的depart_teacher数据类型由int改为varchar

（2）触发器中插入depart_teacher由字符串改为整型
