學(xué)習(xí)mysql事件怎么調(diào)用存儲過程的方法

事件調(diào)用存儲過程主要有三種：

（1）創(chuàng)建事件馬上執(zhí)行，調(diào)用存儲過程

CREATE EVENT if not exists Event_Stat_Daily
on schedule EVERY 1 DAY
on completion preserve
do call cp_Stat_VideoData();

（2）每天定時執(zhí)行事件，調(diào)用存儲過程

CREATE EVENT Event_Stat_Daily
ON SCHEDULE EVERY 1 DAY STARTS '2017-03-01 02:00:00'
ON COMPLETION PRESERVE
ENABLE
DO call cp_Stat_VideoData();

（3）沒有調(diào)用方法或者存儲過程，直接在事件里面邏輯操作

DELIMITER CREATE EVENT e5 ON SCHEDULE EVERY 1 DAY STARTS '2017-03-01 02:00:00' ON COMPLETION PRESERVE DO BEGIN declare yestday date; set yestday=date(date_add(NOW(), interval -1 day)); if exists(select Id from Stat_VideoHits where AddDate = yestday) THEN delete from Stat_VideoHits where AddDate=yestday; end if;

insert into Stat_VideoHits(Id,VideoId,Times,AddDate) select uuid(), VideoId,COUNT(1),AddDate from Coll_VideoHits where AddDate = yestday group by VideoId;

DELETE from Sum_VideoHits;

insert into Sum_VideoHits(Id,VideoId,Times,UpdateDate) select uuid(),VideoId,sum(Times),now() from Stat_VideoHits group by VideoId;

END DELIMITER ;
