Question

我有这个数据库结构：

CREATE TABLE `user` (
  `usr_id` bigint(20) NOT NULL AUTO_INCREMENT,
  `usr_mail` varchar(64) NOT NULL,
  `usr_creationdate` datetime NOT NULL DEFAULT CURRENT_TIMESTAMP,
  PRIMARY KEY (`usr_id`)
);

CREATE TABLE `user_activation` (
  `usract_id` bigint(20) NOT NULL AUTO_INCREMENT,
  `usr_id` bigint(20) NOT NULL,
  `usract_key` text NOT NULL,
  `usract_used` int(11) NOT NULL DEFAULT '0',
  `usract_creationdate` datetime NOT NULL DEFAULT CURRENT_TIMESTAMP,
  `usract_usagedate` datetime NOT NULL DEFAULT CURRENT_TIMESTAMP,
  `usract_expiredate` datetime NOT NULL DEFAULT CURRENT_TIMESTAMP
);


CREATE TRIGGER `USER_INSERT_ADD_ACTIVATION` AFTER INSERT ON `user`
 FOR EACH ROW 
 INSERT INTO user_activation (usr_id, usract_key)
 VALUES (NEW.usr_id, UUID());


CREATE TRIGGER `USRACT_INSER_SET_EXPIREDATA` BEFORE INSERT ON `user_activation`
 FOR EACH ROW 
 SET NEW.usract_expiredate = DATE_ADD(NOW(), INTERVAL 1 DAY);

当我将数据插入表格user_activation时，我的user_activation.usract_expiredate会更新到第二天。如果我将数据插入表user，则会在user_activation中插入一行，但user_activation.usract_expiredate将不会设置为第二天。似乎第二个触发器没有被执行。

我是否对触发器做错了什么？

嗯，你只需要一个触发器即可实现这一目标。

DROP TRIGGER `USRACT_INSER_SET_EXPIREDATA`;
DROP TRIGGER `USER_INSERT_ADD_ACTIVATION`;

CREATE TRIGGER `USER_INSERT_ADD_ACTIVATION` AFTER INSERT ON `user`
 FOR EACH ROW 
 INSERT INTO user_activation (usr_id, usract_key,usract_expiredate)
 VALUES (NEW.usr_id, UUID(),DATE_ADD(NOW(), INTERVAL 1 DAY));

insert =＆gt;之后的MYSQL触发器插入第二个表=＆gt;在插入触发器不工作之前
