--echo #########################################################################
# 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.
