create table examinfo( id int auto_increment not null, endtime datetime, primary key(id) );
3 插入数据:
insert into examinfo values('1','2011-4-23 23:26:50');
4 创建存储过程test
CREATE PROCEDURE test () BEGIN update examinfo SET endtime = now() WHERE id = 1; END; 5、
创建event e_test CREATE EVENT if not exists e_test on schedule every 30 second on completion preserve do call test(); 6、
查看event是否开启: show variables like '%sche%'; 将事件计划开启: set global event_scheduler=1; 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; 7、运行查询结果即可出现想要的结果。
