mysql定时任务用到存储过程和定时任务

 1 /*删除存储过程*/
 2 drop procedure if exists proc_sendAllMsg; 
 3 /*创建存储过程*/ 
 4 CREATE PROCEDURE proc_sendAllMsg()
 5 BEGIN
 6 /*先插入*/
 7 INSERT t_base_message (sid,mid)
 8 SELECT a.id,b.id from t_base_student  a 
 9 INNER JOIN t_app_message b 
10 where a.School_id = 1 and  b.sendtime<=NOW() and b.sendstatus = 0;
11 UPDATE t_app_message  SET sendstatus = 1 where sendtime <=NOW();
12 UPDATE t_app_message  SET showstatus = 1 where endtime <=NOW();
13 end 
14 
15 /*指定数据库*/ 
16 use xscp;
17 /*删除原有的定时任务*/
18 drop event if exists event_sendAllMsg;  
19 
20 CREATE EVENT event_sendAllMsg ON SCHEDULE EVERY 30 second starts  '2017-12-11 00:00:00' 
21 DO 
22 CALL proc_sendAllMsg; /*调用存储过程*/

1 查看event是否开启 : SHOW VARIABLES LIKE '%event_sche%';
2 将事件计划开启 : SET GLOBAL event_scheduler = 1;
3 将事件计划关闭 : SET GLOBAL event_scheduler = 0;
4 关闭事件任务 : ALTER EVENT eventName ON COMPLETION PRESERVE DISABLE;
5 开启事件任务 : ALTER EVENT eventName ON COMPLETION PRESERVE ENABLE;
6 查看事件任务 : SHOW EVENTS ;
