问题
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'
What privileges do I need?
回答1:
The information_schema tables are all read only, there is no way to delete any rows there.
To drop an event, use the DROP EVENT statement.
