MySQL用户权限导致的创建Trigger失败

时间:2022-03-19 17:17:08

说来惭愧,MySQL一直处于只会用,不怎么理解的阶段。甚至是一些较为深层次的管理,都不怎么熟悉,得加强啊!

近日,系统测试,使用MySQL数据库,需要在某个表上创建触发器,数据库是在本机安装。但是,无论如何都无法创建触发器,后台错误信息如下:

分析错误信息:TRIGGER command denied to user 'root'@'mortimer-PC' for table 't_user',看起来是不允许root用户在t_user表上执行TRIGGER命令,为啥不允许?
分析下,首先怀疑是否驱动的问题,因为,驱动确实存在不匹配的问题,驱动的版本较低(针对5.0),而服务器版本为5.5,替换驱动之后问题依旧。

其次,分析错误信息本身,不允许执行神马命令,看起来貌似是权限问题,Navicat连接数据库,查看用户权限,发现用户“root@%”的“Trigger”一栏未选中!而此次连接的用户,看起来是“root@mortimer-PC”,因此,“root@localhost”的规则,貌似不会生效,估计是此原因,造成无法创建触发器。

调整“root@%”用户的权限,选中“Trigger”栏,重启MySQL服务,重新连接MySQL,创建触发器,OK!
