可以给mysql建个定时任务
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 = '110';
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;
开户事件任务
alter event e_test ON COMPLETION PRESERVE ENABLE;
