我是靠谱客的博主粗暴钢笔，最近开发中收集的这篇文章主要介绍sqlserver2005 行列转换实现方法，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

复制代码代码如下:

--Create Company Table 
Create Table Company 
( 
ComID varchar(50) primary key, 
ComName nvarchar(50) not null, 
ComNumber varchar(50) not null, 
ComAddress nvarchar(200), 
ComTele varchar(50) 
) 
--Create Product Table 
Create Table Product 
( 
ProductID varchar(50) primary key, 
ComID varchar(50) not null, 
ProName nvarchar(200) not null, 
ProNumber int not null 
) 
select * from product 
--insert into table value 
insert Company select('58C0F3FD-7B98-4E74-A1A8-7B144FCB8707','CompanyOne','SH19991028','ShangHai','98765432112')
