使用sql实现表90度旋转（矩阵转置）

--创建测试表

CREATE TABLE #a(lb VARCHAR(2),A MONEY,B MONEY,C MONEY)

INSERT INTO #a( lb,A,B,C) VALUES (\'X1\',1,2,3)

INSERT INTO #a( lb,A,B,C) VALUES (\'X2\',4,5,6)

INSERT INTO #a( lb,A,B,C) VALUES (\'X3\',7,8,9)

INSERT INTO #a( lb,A,B,C) VALUES (\'X4\',10,11,12)

INSERT INTO #a( lb,A,B,C) VALUES (\'X5\',13,14,15)

--查一下

SELECT * FROM #a

--90度旋转

SELECT * FROM

(

SELECT [ABC],lb,[data] FROM

(SELECT lb, A, B, C FROM #a ) p

UNPIVOT

([data] FOR [ABC] IN (A, B, C))AS unpvt

) T

PIVOT

(SUM([data])  FOR lb in ([X1],[X2],[X3],[X4],[X5]))AS pt

DROP TABLE #a
