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
复制代码 代码如下:
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;
