DROP PROCEDURE IF EXISTS e_test |
CREATE PROCEDURE e_test()
BEGIN
update hb_hongbao set addtime=SYSDATE(15) where SYSDATE(15)>over_time and status=1;
IF EXISTS(SELECT id FROM hb_hongbao WHERE SYSDATE(15) < over_time and status=1) THEN
UPDATE hb_hongbao2 SET addtime = SYSDATE(15) WHERE uid NOT IN (SELECT id FROM hb_hongbao WHERE SYSDATE(15) < over_time and status=1);
END IF;
END
|
DELIMITER ;
#超时改变hb_hongbao时间 改变hb_hongbao2时间
select `name` from mysql.proc where db = \'hongbao\' and `type` = \'PROCEDURE\';
#删除存储过程
DROP PROCEDURE e_test;
2.创建定时器取名为event_test
SET GLOBAL event_scheduler = 1;
#开启event_scheduler sql指令是否开启
SHOW VARIABLES LIKE \'%event_scheduler%\';
CREATE EVENT IF NOT EXISTS event_test
ON SCHEDULE EVERY 1 SECOND STARTS \'2018-12-19 11:00:00\'
ON COMPLETION PRESERVE
DO CALL e_test();
1 SECOND,3 minute,5 hour,9 day,1 month,1 quarter(季度),1 year
创建一个定时器,2018-12-19 11:00:00开始执行,每间隔1秒触发一次事件,即每个一秒执行一次上面定义的e_test这个存储过程。
select name from mysql.event;
查看所有定时器名字
DROP EVENT [IF EXISTS] event_test;
删除定时任务
3.这个是最简单但是也是最重要的,我们要手动的启动这个定时器,要不然是没法工作的。
ALTER EVENT event_test ON
COMPLETION PRESERVE ENABLE;
