WL#1034 (Internal CRON)
This patch adds INFORMATION_SCHEMA.EVENTS table with the following format:
EVENT_CATALOG - MYSQL_TYPE_STRING (Always NULL)
EVENT_SCHEMA - MYSQL_TYPE_STRING (the database)
EVENT_NAME - MYSQL_TYPE_STRING (the name)
DEFINER - MYSQL_TYPE_STRING (user@host)
EVENT_BODY - MYSQL_TYPE_STRING (the body from mysql.event)
EVENT_TYPE - MYSQL_TYPE_STRING ("ONE TIME" | "RECURRING")
EXECUTE_AT - MYSQL_TYPE_TIMESTAMP (set for "ONE TIME" otherwise NULL)
INTERVAL_VALUE - MYSQL_TYPE_LONG (set for RECURRING otherwise NULL)
INTERVAL_FIELD - MYSQL_TYPE_STRING (set for RECURRING otherwise NULL)
SQL_MODE - MYSQL_TYPE_STRING (for now NULL)
STARTS - MYSQL_TYPE_TIMESTAMP (starts from mysql.event)
ENDS - MYSQL_TYPE_TIMESTAMP (ends from mysql.event)
STATUS - MYSQL_TYPE_STRING (ENABLED | DISABLED)
ON_COMPLETION - MYSQL_TYPE_STRING (NOT PRESERVE | PRESERVE)
CREATED - MYSQL_TYPE_TIMESTAMP
LAST_ALTERED - MYSQL_TYPE_TIMESTAMP
LAST_EXECUTED - MYSQL_TYPE_TIMESTAMP
EVENT_COMMENT - MYSQL_TYPE_STRING
SQL_MODE is NULL for now, because the value is still not stored in mysql.event .
Support will be added as a fix for another bug.
This patch also adds SHOW [FULL] EVENTS [FROM db] [LIKE pattern]
1. SHOW EVENTS shows always only the events on the same user,
because the PK of mysql.event is (definer, db, name) several
users may have event with the same name -> no information disclosure.
2. SHOW FULL EVENTS - shows the events (in the current db as SHOW EVENTS)
of all users. The user has to have PROCESS privilege, if not then
SHOW FULL EVENTS behave like SHOW EVENTS.
3. If [FROM db] is specified then this db is considered.
4. Event names can be filtered with LIKE pattern.
SHOW EVENTS returns table with the following columns, which are subset of
the data which is returned by SELECT * FROM I_S.EVENTS
Db
Name
Definer
Type
Execute at
Interval value
Interval field
Starts
Ends
