MySQL 5.1.6 and later provides several SQL statements for working with scheduled events:
New events are defined using the
EVENT statement. See 「
CREATE EVENT Syntax」.
The definition of an existing event can be changed by means of
ALTER EVENT statement. See
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
DROP EVENT Syntax」. (Whether an event persists past
the end of its schedule also depends on its
COMPLETION clause, if it has one. See
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
「The Event Scheduler and MySQL Privileges」.
