The MySQL Event Scheduler manages the scheduling and execution of events, that is, tasks that run according to a schedule. The following discussion covers the Event Scheduler and is divided into the following sections:
Section 20.4.1, “Event Scheduler Overview”, provides an introduction to and conceptual overview of MySQL Events.
Section 20.4.3, “Event Syntax”, discusses the SQL statements for creating, altering, and dropping MySQL Events.
Section 20.4.4, “Event Metadata”, shows how to obtain information about events and how this information is stored by the MySQL Server.
Section 20.4.6, “The Event Scheduler and MySQL Privileges”, discusses the privileges required to work with events and the ramifications that events have with regard to privileges when executing.
Stored routines require the
event table in the
mysql database. This table is created during the
MySQL 5.5 installation procedure. If you are upgrading
to MySQL 5.5 from an earlier version, be sure to update
your grant tables to make sure that the
table exists. See Section 4.4.7, “mysql_upgrade — Check and Upgrade MySQL Tables”.
