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] 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; |
