Mysql 定时任务

1.检查数据库是否开启

navicat 执行：**SHOW VARIABLES LIKE 'event_scheduler';**

2.如果没有开启泽需要执行：**SET GLOBAL event_scheduler = ON;**

3.添加任务

DELIMITER $$

DROP EVENT IF EXISTS deletecase;

CREATE EVENT deletecase

ON SCHEDULE EVERY 300 SECOND

ON COMPLETION PRESERVE

DO BEGIN

delete from test WHERE TO_DAYS(now())-TO_DAYS(CREATE_TIME)>180;

END$$

DELIMITER ;

4.查看任务状态：

SELECT * FROM information_schema.EVENTS
