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;
