mysql利用存储过程 同实例数据库迁移数据

网上有很多利用存储过程迁移数据，很多是利用游标添加数据 但是 使用游标添加数据 ，会产生数据丢失的问题，，所以在在网上找了相关方法 把相关数据导入到临时表中，我这里是导入到视图中

mysql提供了三张插入的方式：

类别一、 如果两张张表（导出表和目标表）的字段一致，并且希望插入全部数据，可以用这种方法：

INSERT INTO目标表 SELECT  * FROM来源表 ;

类别二、 如果只希望导入指定字段，可以用这种方法：

INSERT INTO目标表 (字段1, 字段2, ...)SELECT字段1, 字段2, ...FROM来源表 ;

类别三、 方法二的升级版 ，从原表取出部分字段数据的同时，目标表有新的字段也需要数据；

insert into 目标表 (列名1,列名2,列名3) values(列1,列2,(select 列3 from 原表));

我这里采用的是第二种方式；
代码如下；
我这里设计带了行列转换 所以才是这样
