MySQL 5.1 中新增了事件调度器这一个功能。可以实现类似于SQL Server的Job功能。
1.语法：
CREATE EVENT [IF NOT EXISTS] event_nameON SCHEDULE schedule [ON COMPLETION [NOT] PRESERVE][ENABLE | DISABLE][COMMENT 'comment']DO sql_statement;View Code
其中schedule的语句可以表示为：
AT TIMESTAMP [+ INTERVAL]| EVERY INTERVAL [STARTS TIMESTAMP] [ENDS TIMESTAMP]View Code
interval的单位可以有如下几种：
YEAR | QUARTER | MONTH | DAY | HOUR | MINUTE |WEEK | SECOND | YEAR_MONTH | DAY_HOUR | DAY_MINUTE | DAY_SECOND | HOUR_MINUTE | HOUR_SECOND | MINUTE_SECONDView Code
2.开启、关闭事件调度器：
在使用这个功能之前必须确保event_scheduler已开启.
/*开启*/SET GLOBAL event_scheduler = 1;-- 或SET GLOBAL event_scheduler = ON;/*关闭*/SET GLOBAL event_scheduler = 0;-- 或SET GLOBAL event_scheduler = OFF; View Code
3.示例：
创建测试数据库：
CREATE TABLE tst_event (createtime DATETIME);View Code
创建测试用存储过程：
/*创建测试用存储过程*/CREATE PROCEDURE msp_TestEvent()BEGIN INSERT INTO tst_event VALUES (CURRENT_TIMESTAMP);ENDView Code
创建事件调度器：
CREATE EVENT IF NOT EXISTS me_TestEvent ON SCHEDULE EVERY 10 SECOND STARTS '2014-02-28 16:45:00' ENDS DATE_ADD('2014-02-28 16:46:00',INTERVAL 1 SECOND) DO CALL msp_TestEvent();View Code
修改事件调度器：
/*修改EVENT*/ ALTER EVENT me_TestEvent ON SCHEDULE EVERY 10 SECOND STARTS '2014-02-27 16:45:00' ENDS DATE_ADD('2014-02-27 16:46:00',INTERVAL 1 SECOND) DO INSERT INTO tst_event VALUES (CURRENT_TIMESTAMP);View Code
查看事件调度器：
/*查看EVENT*/ show events;-- 或select * from information_schema.events View Code
4.不同时间间隔的调度：
一天后执行调度器：
/*一天后执行调度器T*/ CREATE EVENT e_TestEventON SCHEDULE AT CURRENT_TIMESTAMP + INTERVAL 1 DAYDO CALL msp_TestEvent();View Code
2014-02-28日执行调度器：
/*2014-02-28日执行调度器*/ CREATE EVENT e_TestEventON SCHEDULE AT TIMESTAMP '2014-02-28 00:00:00'DO CALL msp_TestEvent();View Code
每天执行调度器：
/*每天执行调度器*/ CREATE EVENT e_TestEventON SCHEDULE EVERY 1 DAYDO CALL msp_TestEvent();View Code
一天后每天执行调度器：
/*一天后每天执行调度器*/ CREATE EVENT e_TestEventON SCHEDULE EVERY 1 DAYSTARTS CURRENT_TIMESTAMP + INTERVAL 2 DAYDO CALL msp_TestEvent(); View Code
每天执行调度器，10天后停止：
/*每天执行调度器，10天后停止*/ CREATE EVENT e_TestEventON SCHEDULE EVERY 1 DAYENDS CURRENT_TIMESTAMP + INTERVAL 10 DAYDO CALL msp_TestEvent(); View Code
一天后开始，每天执行调度器，10天后停止：
/*一天后开始，每天执行调度器，10天后停止*/ CREATE EVENT e_TestEventON SCHEDULE EVERY 1 DAYSTARTS CURRENT_TIMESTAMP + INTERVAL 1 DAYENDS CURRENT_TIMESTAMP + INTERVAL 10 MONTHDO CALL msp_TestEvent();View Code
每天执行调度器，只执行一次:
/*每天执行调度器，只执行一次*/ CREATE EVENT e_TestEventON SCHEDULE EVERY 1 DAYON COMPLETION NOT PRESERVEDO CALL msp_TestEvent(); View Code
5.删除调度器：
DROP EVENT [IF EXISTS] event_nameView Code
