mysql写个存储过程备份数据

首先准备两张数据表：

　　一张是源数据表：aa_test

　　一张是备份数据表：aa_test_to

表的来源：链接：https://pan.baidu.com/s/1-tZEAYkGgxjdmrocaVvwOA 密码：3246

存储过程的代码：

BEGIN
DECLARE uid varchar(100);
DECLARE u_time varchar(10);
DECLARE u_show VARCHAR(100);
DECLARE U_NAME VARCHAR(100);

DECLARE cur CURSOR FOR select id,static_time,show_dimension,type_name from aa_test;
DECLARE CONTINUE HANDLER FOR NOT FOUND SET @no_record=1;
open cur;
loop_lable:LOOP
FETCH cur into uid,u_time,u_show,u_name;
IF @no_record = 1 THEN
	LEAVE loop_lable;
	END IF;

INSERT INTO aa_test_to (id,static_time,show_dimension,type_name)
VALUES(uid,u_time,u_show,u_name);
END LOOP;
close cur;
END

　　

 然后执行它，就可以成功备份了。
