一个简单的交叉报表_列转行

--列转行小实例
--创建测试表
if object_id(N"test", N"U") is not null
  drop table test
Go
with UnPivotTable as
(
  select 1 as UserNO, "33" as A, "44" AS B, "55" as C
  uNIOn all
  select 2 as UserNO, "23" as A, "34" AS B, "56" as C
)
select * into test from UnPivotTable
go
--创建存储过程
if exists(select name from sysobjects where name = "usp_GetUnPivotInfo")
    drop proc usp_GetUnPivotInfo
go

create proc usp_GetUnPivotInfo
as
declare @sql nvarchar(4000)        
SELECT @SQL=isnull(@SQL+",","")+quotename(Name) FROM syscolumns
WHERE ID=object_id("test") and [name] not in ("UserNO") ORDER BY Colid
SET @SQL="select UserNO,[Attr],[value] from (select * from test) a unpivot ([value] for [Attr] in("+@SQL+"))b"
exec(@SQL);
go

exec usp_GetUnPivotInfo ;
