mysql定时任务

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; 

创建存储过程test 
CREATE PROCEDURE test () 
BEGIN 
INSERT INTO table(end_time) VALUES(now()) ; 
END; 

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

从6月8号开始每天定时执行存储过程：ON SCHEDULE AT TIMESTAMP '2016-06-08 12:00:00'
