RDS时间如何设置每天1点执行调用存储过程

mysql怎么让一个存储过程定时执行 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; 简单实例. 创建表 CREATE TABLE test(endtime DATETIME); 创建存储过程test CREATE PROCEDURE test () BEGIN update examinfo SET endtime = now() WHERE id = 14; 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,将当前时间更新到examinfo表中id=14的记录的endtime字段中去 1) 首先来看一个简单的例子来演示每秒插入一条记录到数据表 USE test; CREATE TABLE aaa (timeline TIMESTAMP); CREATE EVENT e_test_insert ON SCHEDULE EVERY 1 SECOND DO INSERT INTO test.aaa VALUES (CURRENT_TIMESTAMP); 等待3秒钟后，再执行查询看看： mysql> SELECT * FROM aaa; +---------------------+ | timeline | +---------------------+ | 2007-07-18 20:44:26 | | 2007-07-18 20:44:27 | | 2007-07-18 20:44:28 | +---------------------+ 2) 5天后清空test表： CREATE EVENT e_test ON SCHEDULE AT CURRENT_TIMESTAMP + INTERVAL 5 DAY DO TRUNCATE TABLE test.aaa; 3) 2007年7月20日12点整清空test表： CREATE EVENT e_test ON SCHEDULE AT TIMESTAMP '2007-07-20 12:00:00' DO TRUNCATE TABLE test.aaa; 4) 每天定时清空test表： CREATE EVENT e_test ON SCHEDULE EVERY 1 DAY DO TRUNCATE TABLE test.aaa; 5) 5天后开启每天定时清空test表： CREATE EVENT e_test ON SCHEDULE EVERY 1 DAY STARTS CURRENT_TIMESTAMP + INTERVAL 5 DAY DO TRUNCATE TABLE test.aaa; 6) 每天定时清空test表，5天后停止执行： CREATE EVENT e_test ON SCHEDULE EVERY 1 DAY ENDS CURRENT_TIMESTAMP + INTERVAL 5 DAY DO TRUNCATE TABLE test.aaa; 7) 5天后开启每天定时清空test表，一个月后停止执行： CREATE EVENT e_test ON SCHEDULE EVERY 1 DAY STARTS CURRENT_TIMESTAMP + INTERVAL 5 DAY ENDS CURRENT_TIMESTAMP + INTERVAL 1 MONTH DO TRUNCATE TABLE test.aaa; [ON COMPLETION [NOT] PRESERVE]可以设置这个事件是执行一次还是持久执行，默认为NOT PRESERVE。 8) 每天定时清空test表(只执行一次，任务完成后就终止该事件)： CREATE EVENT e_test ON SCHEDULE EVERY 1 DAY ON COMPLETION NOT PRESERVE DO TRUNCATE TABLE test.aaa; [ENABLE | DISABLE]可是设置该事件创建后状态是否开启或关闭，默认为ENABLE。 [COMMENT ‘comment’]可以给该事件加上注释。 三、修改事件(ALTER EVENT) ALTER EVENT event_name [ON SCHEDULE schedule] [RENAME TO new_event_name] [ON COMPLETION [NOT] PRESERVE] [COMMENT 'comment'] [ENABLE | DISABLE] [DO sql_statement] 1) 临时关闭事件 ALTER EVENT e_test DISABLE; 2) 开启事件 ALTER EVENT e_test ENABLE; 3) 将每天清空test表改为5天清空一次： ALTER EVENT e_test ON SCHEDULE EVERY 5 DAY; 四、删除事件(DROP EVENT) 语 法很简单，如下所示： DROP EVENT [IF EXISTS] event_name 例如删除前面创建的e_test事件 DROP EVENT e_test; 当然前提是这个事件存在，否则会产生ERROR 1513 (HY000): Unknown event错误，因此最好加上IF EXISTS DROP EVENT IF EXISTS e_test; create event test ON SCHEDULE AT '2007-09-01 12:00:00' + INTERVAL 1 DAY on completion not preserve do insert into yyy values('hhh','uuu'); 解释：从2007-09-01开始，每天对表yyy在12：00：00进行一个插入操作。而且只执行一次（on completion not preserve ） 我的计划任务为： create event sysplan ON SCHEDULE AT '2010-05-22 23:00:00' + INTERVAL 1 DAY on completion not preserve do truncate table bjproj.ae_tmp; 三、通过设定全局变量event_scheduler 的值即可动态的控制事件调度器是否启用。 查看是否event_scheduler开启mysql> SHOW VARIABLES LIKE '%event%'; 设置开启mysql> SET GLOBAL event_scheduler=ON; 四、例子: 每分钟插入一条日志:DELIMITER //CREATE EVENT user_log_event ON SCHEDULE EVERY 1 MINUTE STARTS '2010-12-27 00:00:00' ON COMPLETION NOT PRESERVE ENABLE DO BEGIN INSERT INTO log SET addtime=NOW();END// 调用存储过程:DELIMITER //CREATE EVENT user_log_event ON SCHEDULE EVERY 1 DAY STARTS '2010-00-00 00:00:00' ON COMPLETION NOT PRESERVE ENABLE DO BEGIN CALL user_log_prov();END//
