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:

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!
