我想实现每隔30秒执行以下下面sql
- update userinfo SET endtime = now() WHERE id ='155';
?
如何让mysql定时执行上面的sql语句呢！
?
一、查看event是否开启
show variables like '%sche%';
开启event_scheduler
set global event_scheduler =1;
二、创建存储过程test
CREATE PROCEDURE test ()
BEGIN
update userinfo SET endtime = now() WHERE id = '155';
END;
三、创建event e_test
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
alter event e_test ON COMPLETION PRESERVE DISABLE;
