获得 information_schema mysql 的权限
问题描述：
如果我打开 MySQL Administrator 并尝试从数据库 information_schema 的表 events 中删除一个事件，我会收到此错误:
If I open MySQL Administrator and I try to delete one event from the table events of the database information_schema I get this error:
Access denied for user 'root'@'localhost' to database 'information_schema'
我需要什么权限?
答
information_schema 表都是只读的，无法删除任何行.
The information_schema tables are all read only, there is no way to delete any rows there.
要删除事件，请使用 DROP EVENT 语句.
To drop an event, use the DROP EVENT statement.
