19.2. Event Scheduler Syntax

MySQL 5.1.6 and later provides several SQL statements for working with scheduled events:

New events are defined using the CREATE EVENT statement. See 項19.2.1. 「CREATE EVENT Syntax」.
The definition of an existing event can be changed by means of the ALTER EVENT statement. See 項19.2.2. 「ALTER EVENT Syntax」.
When a scheduled event is no longer wanted or needed, it can be deleted from the server by its definer using the DROP EVENT statement. See 項19.2.3. 「DROP EVENT Syntax」. (Whether an event persists past the end of its schedule also depends on its ON COMPLETION clause, if it has one. See 項19.2.1. 「CREATE EVENT Syntax」.)

An event can be deleted by any user having the EVENT privilege for the database on which the event is defined. Prior to MySQL 5.12, a user other than the definer required privileges on the mysql.event table. See 項19.5. 「The Event Scheduler and MySQL Privileges」.
