12.4.5.19. SHOW EVENTS Syntax

SHOW EVENTS [{FROM | IN} schema_name]
    [LIKE 'pattern' | WHERE expr]

In its simplest form, SHOW EVENTS lists all of the events in the current schema: 

mysql> SELECT CURRENT_USER(), SCHEMA();
+----------------+----------+
| CURRENT_USER() | SCHEMA() |
+----------------+----------+
| jon@ghidora    | myschema |
+----------------+----------+
1 row in set (0.00 sec)

mysql> SHOW EVENTS\G
*************************** 1. row ***************************
                  Db: myschema
                Name: e_daily
             Definer: jon@ghidora
           Time zone: SYSTEM
                Type: RECURRING
          Execute at: NULL
      Interval value: 10
      Interval field: SECOND
              Starts: 2006-02-09 10:41:23
                Ends: NULL
              Status: ENABLED
          Originator: 0
character_set_client: latin1
collation_connection: latin1_swedish_ci
  Database Collation: latin1_swedish_ci

To see events for a specific schema, use the FROM clause. For example, to see events for the test schema, use the following statement: 

SHOW EVENTS FROM test;

The LIKE clause, if present, indicates which event names to match. The WHERE clause can be given to select rows using more general conditions, as discussed in Section 19.28, “Extensions to SHOW Statements”.

SHOW EVENTS output has the following columns:

  • Db: The schema (database) on which the event is defined.

  • Name: The name of the event.

  • Time zone: The event time zone, which is the time zone used for scheduling the event and that is in effect within the event as it executes. The default value is SYSTEM.

  • Definer: The account of the user who created the event, in 'user_name'@'host_name' format.

  • Type: The event repetition type, either ONE TIME (transient) or RECURRING (repeating).

  • Execute At: The date and time when a transient event is set to execute. Shown as a DATETIME value.

    For a recurring event, the value of this column is always NULL.

  • Interval Value: For a recurring event, the number of intervals to wait between event executions.

    For a transient event, the value of this column is always NULL.

  • Interval Field: The time units used for the interval which a recurring event waits before repeating.

    For a transient event, the value of this column is always NULL.

  • Starts: The start date and time for a recurring event. This is displayed as a DATETIME value, and is NULL if no start date and time are defined for the event.

    For a transient event, this column is always NULL.

  • Ends: The end date and time for a recurring event. This is displayed as a DATETIME value, and defaults to NULL if no end date and time is defined for the event.

    For a transient event, this column is always NULL.

  • Status: The event status. One of ENABLED, DISABLED, or SLAVESIDE_DISABLED.

    SLAVESIDE_DISABLED indicates that the creation of the event occurred on another MySQL server acting as a replication master and replicated to the current MySQL server which is acting as a slave, but the event is not presently being executed on the slave.

  • Originator: The server ID of the MySQL server on which the event was created. Defaults to 0.

  • character_set_client is the session value of the character_set_client system variable when the routine was created. collation_connection is the session value of the collation_connection system variable when the routine was created. Database Collation is the collation of the database with which the routine is associated.

For more information about SLAVE_DISABLED and the Originator column, see Section 16.4.1.8, “Replication of Invoked Features”.

The event action statement is not shown in the output of SHOW EVENTS. Use SHOW CREATE EVENT or the INFORMATION_SCHEMA.EVENTS table.

Times displayed by SHOW EVENTS are given in the event time zone, as discussed in Section 18.4.4, “Event Metadata”.

The columns in the output of SHOW EVENTS are similar to, but not identical to the columns in the INFORMATION_SCHEMA.EVENTS table. See Section 19.20, “The INFORMATION_SCHEMA EVENTS Table”.
