# Ensure that the INFORMATION_SCHEMA.EVENTS table has the following columns,
# in the following order:
#
# EVENT_CATALOG       always NULL
# EVENT_SCHEMA        The name of the schema (database) to which this
#                     event belongs.
# EVENT_NAME          The name of the event.
# DEFINER             The user who created the event.
#                     'user_name'@'host_name'  format!
# TIME_ZONE           The time zone in effect when schedule for the event was
#                     last modified
# EVENT_BODY          The language used for the statements in the event's
#                     DO clause. (always SQL)
# EVENT_DEFINITION    The text of the SQL statement making up the event's
#                     DO clause.
# EVENT_TYPE          One of the two values ONE TIME or RECURRING.
# EXECUTE_AT          one-time event: DATETIME value specified in the AT clause
#                                     of the CREATE EVENT statement used to
#                                     create the event
#                     or of the last ALTER EVENT statement that modified
#                     the event.
# INTERVAL_VALUE      recurring events; numeric portion of the event's
#                     EVERY clause.
# INTERVAL_FIELD      recurring events: units portion of the EVERY clause
#                     governing the timing of the event, prefixed with
#                     'INTERVAL_'.  Example: 'INTERVAL_DAY'
# SQL_MODE            The SQL mode in effect at the time the event was created
#                     or altered.
# STARTS              For recurring event whose definition includes a STARTS
#                     clause, this column contains the corresponding
#                     DATETIME value. If there is no STARTS clause affecting
#                     the timing of the event, this column is empty.
# ENDS                For a recurring event whose definition includes a ENDS
#                     clause, this column contains the corresponding DATETIME
#                     value. If there is no ENDS clause affecting the timing
#                     of the event, this column contains NULL.
# STATUS              ENABLED, DISABLED or SLAVESIDE_DISABLED
# ON_COMPLETION       PRESERVE or NOT PRESERVE.
# CREATED             Date and time of event creation
# LAST_ALTERED        Date and time of the last event modification
#                     never modified -> value = CREATED
# LAST_EXECUTED       Date and time of start of last event execution
#                     never executed -> value IS NULL.
# EVENT_COMMENT       The text of a comment. Default: empty string.
# ORIGINATOR          The server ID of the MySQL server on which the event was
#                     created; used in replication. Default: 0
# CHARACTER_SET_CLIENT Session value of the character_set_client system variable
#                      when the event was created.
# COLLATION_CONNECTION Session value of the collation_connection system
#                      variable when the event was created.
# DATABASE_COLLATION  Collation of the database with which the event
#                     is associated.
