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 25.4.1, “Event Scheduler Overview”, provides an introduction to and conceptual overview of MySQL Events.
Section 25.4.3, “Event Syntax”, discusses the SQL statements for creating, altering, and dropping MySQL Events.
Section 25.4.4, “Event Metadata”, shows how to obtain information about events and how this information is stored by the MySQL Server.
Section 25.4.6, “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 events data dictionary table in the mysql system database. This table is created during the MySQL 8.0 installation procedure. If you are upgrading to MySQL 8.0 from an earlier version, be sure to perform the upgrade procedure to make sure that your system database is up to date. See Section 2.11, “Upgrading MySQL”.
You may find the MySQL Event Scheduler User Forum of use when working with scheduled events.
There are some restrictions on the use of events; see Section 25.8, “Restrictions on Stored Programs”.
Binary logging for events takes place as described in Section 25.7, “Stored Program Binary Logging”.
