mysql定时脚本（event），类似oracle的job

 

我有2张表：tb_push_data 和 tb_push_data_log

现在需要每隔一段时间将tb_push_data 符合条件的

数据备份到表 tb_push_data_log

  www.2cto.com  

--------------------------------------------------------------------------

 

一、创建存储过程

 

DELIMITER $$

 

USE `push_server_db`$$

 

DROP PROCEDURE IF EXISTS `proc_tb_push_data_backup`$$

 

CREATE DEFINER=`root`@`localhost` PROCEDURE `proc_tb_push_data_backup`()

BEGIN

    START TRANSACTION;

    

    INSERT INTO tb_push_data_log(id,created_date,data_id,gps,have_image,message,recv_name,
recv_username,send_name,send_username,STATUS,tool,updated_date,uri,image_path,log_time)

    SELECT id,created_date,data_id,gps,have_image,message,recv_name,recv_username,send_name,
send_username,STATUS,tool,updated_date,uri,image_path,NOW()

    FROM tb_push_data WHERE STATUS = ‘ALREADY_RECEIVE‘;

    DELETE FROM tb_push_data WHERE STATUS = ‘ALREADY_RECEIVE‘;

    

    COMMIT;

    END$$

 

DELIMITER ;

 

二、创建MYSQL事件

 

DELIMITER $$

 

CREATE event event_tb_push_data_backup

 

ON SCHEDULE

 

EVERY 5 MINUTE

 

STARTS NOW()

 

DO

 

BEGIN

 

CALL event_tb_push_data_backup();

 

END;

 

DELIMITER ;

 

三、验证并修改数据库是否开启了事件  www.2cto.com  

 

大家按照例子做完以后，可能发现没有运行event，原因大都是因为

event_scheduler状态没打开

 

查看event_scheduler状态

 

show variables like ‘%sche%‘;

 

修改event_scheduler状态

 

set global event_scheduler=1;
