php - 更新后的Mysql触发器插入到另一个有条件的表中

Question

更新表 student_approve insert data to table notification 但在第 5 行发生错误

DROP TRIGGER IF EXISTS  `student_approve`;
CREATE TRIGGER `student_approve` AFTER UPDATE ON `student_info` 
FOR EACH ROW 
BEGIN
IF NEW.student_approval LIKE '1' THEN
INSERT INTO `notifications` (user_to_notify,who_fired_event,noti_event_id)VALUES(NEW.registered_by,1,2);
END IF;
END

Answer 1

LIKE 不能用于简单的比较，它只支持在 WHERE 子句中。不要忘记更改分隔符。

DROP TRIGGER IF EXISTS  `student_approve`;
DELIMITER //
CREATE TRIGGER `student_approve` AFTER UPDATE ON `student_info` 
FOR EACH ROW 
BEGIN
   IF NEW.student_approval = '1' THEN
     INSERT INTO `notifications` (user_to_notify,who_fired_event,noti_event_id) VALUES(NEW.registered_by,1,2);
   END IF;
END//
DELIMITER ;

会修复语法错误，但我当然无法判断结果是否是您想要的。
