SQL Server 2008的透視查詢

Question

我有數據在SQL Server 2008中的表看起來像這樣：

我要轉動它看起來像這樣：

基本上我想對ReadTime和Coater進行分組，然後在DataType列上旋轉。有人可以幫我用T-SQL來做到這一點嗎？

Answer 1

也許這將幫助：

測試數據：

DECLARE @tbl TABLE 
(
    ReadTime DATETIME, 
    Coater VARCHAR(100), 
    Value FLOAT, 
    DateType VARCHAR(100) 
) 
INSERT INTO @tbl VALUES('2012-10-01 13:28:01','PBG11A-COATER',1,'FCDAOpside473') 
INSERT INTO @tbl VALUES('2012-10-01 13:28:01','PBG11A-COATER',1,'FCDABackside473') 
INSERT INTO @tbl VALUES('2012-10-01 13:28:01','PBG11A-COATER',0,'FCDAOpside472') 
INSERT INTO @tbl VALUES('2012-10-01 13:28:01','PBG11A-COATER',0.9,'FCDABackside472') 
INSERT INTO @tbl VALUES('2012-10-01 13:28:01','PBG11B-COATER',1,'FCDAOpside473') 
INSERT INTO @tbl VALUES('2012-10-01 13:28:01','PBG11B-COATER',2,'FCDABackside472') 
INSERT INTO @tbl VALUES('2012-10-01 13:28:01','PBG11B-COATER',2.9,'FCDAOpside472') 
INSERT INTO @tbl VALUES('2012-10-01 13:28:01','PBG11B-COATER',0,'FCDABackside473') 

INSERT INTO @tbl VALUES('2012-10-01 13:28:41','PBG11A-COATER',1,'FCDAOpside473') 
INSERT INTO @tbl VALUES('2012-10-01 13:28:41','PBG11A-COATER',1,'FCDABackside473') 
INSERT INTO @tbl VALUES('2012-10-01 13:28:41','PBG11A-COATER',0,'FCDAOpside472') 
INSERT INTO @tbl VALUES('2012-10-01 13:28:41','PBG11A-COATER',0.9,'FCDABackside472') 
INSERT INTO @tbl VALUES('2012-10-01 13:28:41','PBG11B-COATER',1,'FCDAOpside473') 
INSERT INTO @tbl VALUES('2012-10-01 13:28:41','PBG11B-COATER',2,'FCDABackside472') 
INSERT INTO @tbl VALUES('2012-10-01 13:28:41','PBG11B-COATER',2.9,'FCDAOpside472') 
INSERT INTO @tbl VALUES('2012-10-01 13:28:41','PBG11B-COATER',0,'FCDABackside473') 

查詢：

SELECT 
    * 
FROM 
(
    SELECT 
     ReadTime, 
     Coater, 
     DateType, 
     Value 
    FROM @tbl AS tbl 
) AS SourceTable 
PIVOT 
    (
     MIN(Value) 
     FOR DateType IN 
        (
         [FCDAOpside472], 
         [FCDAOpside473], 
         [FCDABackside472], 
         [FCDABackside473] 
        )
