每天往一个表里面插入两条数据，但日期不同
INSERT INTO test(`id`, `art_training_institutions`, `places_for_performances`, `script_entertainment`, `video_game_hall`, `stage`, `ktv`, `Internet_bar`, `status`, `statistics_time`, `insert_time`) VALUES (100, 2253, 61, 546, 90, 51, 897, 1961, 1, '2022-08-24', '2022-08-25 14:00:00'); INSERT INTO test(id`, `art_training_institutions`, `places_for_performances`, `script_entertainment`, `video_game_hall`, `stage`, `ktv`, `Internet_bar`, `status`, `statistics_time`, `insert_time`) VALUES (101, 0, 0, 0, 0, 0, 0, 0, 2, '2022-08-24', '2022-08-25 14:00:00');
如果没有其他调度或者不想每天自己手动执行，可以考虑使用MySQL自带的定时器来做
首先
show variables like '%sche%';
如果你的是OFF
那就需要开启：
set global event_scheduler=1;
根据自己的需求，修改存储函数
CREATE PROCEDURE insert_monitor() INSERT INTO test( `art_training_institutions`, `places_for_performances`, `script_entertainment`, `video_game_hall`, `stage`, `ktv`, `Internet_bar`, `status`, `statistics_time`) select 2253, 61, 546, 90, 51, 897, 1961, 1, CURRENT_DATE union all select 0, 0, 0, 0, 0, 0, 0, 2, CURRENT_DATE
-- 每天0点执行 create event if not EXISTS my_monitor on schedule every 1 DAY STARTS date(CURRENT_DATE+1) on completion preserve do call insert_monitor();
show events; 或者 select * from mysql.event;
删除
drop event my_monitor
如果不想删除，可以考虑将它关闭
-- 关闭 alter event my_monitor on COMPLETION PRESERVE DISABLE; -- 开启 alter event my_monitor on COMPLETION PRESERVE ENABLE;
每天凌晨一点执行定时任务
on schedule every 1 DAY STARTS DATE_ADD(DATE(CURRENT_DATE+1), interval 1 hour) on schedule EVERY 1 DAY STARTS date_add(date( ADDDATE(curdate(),1)),interval 1 hour)
特定的日期特定的时间点执行定时任务
ON SCHEDULE at '2019-10-10 19:14:10'
每五分钟执行一次定时任务
ON SCHEDULE EVERY 5 MINUTE STARTS CURDATE()
每小时执行一次定时任务
ON SCHEDULE EVERY 1 HOUR STARTS CURDATE()
at 特定时间执行，every 重复执行
参考 MySQL - 定时任务（每天凌晨1点、每小时、每分钟、某一时间点）
周期性
定时器,一直执行
从现在开始每隔x天执行一次
DROP EVENT IF EXISTS user_event ; CREATE EVENT user_event ON SCHEDULE EVERY 9 DAY STARTS NOW() DO call user_procedure();
每天凌晨1点执行
DROP EVENT IF EXISTS user_event ; CREATE EVENT user_event on schedule EVERY 1 DAY STARTS date_add(date( ADDDATE(curdate(),1)),interval 1 hour) DO call user_procedure();
每个月的一号凌晨1 点执行
DROP EVENT IF EXISTS 定时器名称 ; CREATE EVENT user_event ON schedule every 1 month starts date_add(date_add(date_sub(curdate(),interval day(curdate())-1 day),interval 1 month),interval 1 hour) DO call user_procedure();
每个季度一号的凌晨1点执行
DROP EVENT IF EXISTS user_event ; CREATE EVENT user_event ON schedule every 1 quarter starts date_add(date_add(date(concat(year(curdate()),'-',elt(quarter(curdate()),1,4,7,10),'-',1)),interval 1 quarter),interval 1 hour) DO call user_procedure();
每年1月1号凌晨1点执行
DROP EVENT IF EXISTS user_event ; CREATE EVENT user_event ON schedule every 1 quarter starts date_add(date_add(date(concat(year(curdate()),'-',elt(quarter(curdate()),1,4,7,10),'-',1)),interval 1 quarter),interval 1 hour) DO call user_procedure();
周期一次性
定时器执行很多次后在满足某个条件,定时器结束
从现在开始每天执行一次，5天后停止执行
DROP EVENT IF EXISTS user_event ;
CREATE EVENT user_event
ON SCHEDULE EVERY 1 DAY
ENDS CURRENT_TIMESTAMP + INTERVAL 5 DAY
DO call user_procedure();
从现在开始5天后开始执行，一个月后停止执行
DROP EVENT IF EXISTS user_event ;
CREATE EVENT user_event
ON SCHEDULE EVERY 1 DAY
STARTS CURRENT_TIMESTAMP + INTERVAL 5 DAY
ENDS CURRENT_TIMESTAMP + INTERVAL 1 MONTH
DO call user_procedure();
一次性
满足指定条件时只会执行一次定时器,然后定时器被清除
在未来指定时间点执行一次
DROP EVENT IF EXISTS user_event ;
CREATE EVENT user_event
ON SCHEDULE AT TIMESTAMP '2021-09-24 18:26:00'
ON COMPLETION NOT PRESERVE
DO call user_procedure();
在2021-09-24 18:26:00时候执行user_procedure()存储过程一次之后,该定时器被系统清除从现在开始1小时后执行一次
DROP EVENT IF EXISTS user_event ;
CREATE EVENT user_event
ON SCHEDULE AT CURRENT_TIMESTAMP + INTERVAL 1 HOUR
ON COMPLETION NOT PRESERVE
DO call user_procedure();
开启和关闭指定定时器
alter event user_event on completion preserve enable; -- 开启定时任务 alter event user_event on completion preserve disable; -- 关闭定时任务
