mysql定时任务简单例子

 

    如果要每30秒执行以下语句：[sql] update userinfo set endtime = now() WHERE id = '110';  可以给mysql建个定时任务，具体方法如下：[sql] delimiter //   /* 设定语句终结符为 //，因存储过程语句用;结束 */  

 

 

一、查看event是否开启

[sql] show variables like '%sche%';  开启event_scheduler[sql] set global event_scheduler =1;  

 

 

二、创建存储过程test

[sql] CREATE PROCEDURE test ()  BEGIN  update userinfo set endtime = now() where id = '110';  END;  

 

 

三、创建event e_test

[sql] create event if not exists e_test  on schedule every 30 second  on completion preserve  do call test();  每隔30秒将执行存储过程test关闭事件任务[sql] alter event e_test ON COMPLETION PRESERVE DISABLE;  开户事件任务[sql] alter event e_test ON COMPLETION PRESERVE ENABLE;
