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

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

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

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;
