MySQL用户权限导致的创建Trigger失败

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

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。
