与SUM的SQL数据透视表

Question

我试图将以下SQL代码修改为数据透视表。原始数据看起来像这样：

PerilCode  B    C   BI 
EQ   179166451986 27296144046 9067728654 
WS   182394050346 28745459712 9148728654 
SL   114374574342 12703142574 293860386 
TC   182394050346 28745459712 9148728654 
WF   182394050346 28745459712 9148728654 
FF   182394050346 28745459712 9148728654 
ST   182394050346 28745459712 9148728654 

的代码如下：

SELECT 
PL.PerilCode, 
SUM(ReplacementValueA) AS 'B', 
SUM(ReplacementValueC) AS 'C', 
SUM(ReplacementValueD) AS 'BI' 

FROM [SE-SQLTO-0300].[AIRExposure_London].[dbo].[tLocation] L 

INNER JOIN [SE-SQLTO-0300].[AIRExposure_London].[dbo].[tExposureSet] ES ON L.ExposureSetSID = ES.ExposureSetSID 
INNER JOIN [SE-SQLTO-0300].[AIRProject].[dbo].[tExposureViewDefinition] EVD ON ES.ExposureSetSID = EVD.ExposureSetSID 
INNER JOIN [SE-SQLTO-0300].[AIRProject].[dbo].[tExposureView] EV ON EVD.ExposureViewSID = EV.ExposureViewSID 
INNER JOIN [SE-SQLTO-0300].[AIRProject].[dbo].[tProjectExposureViewXref] PEV ON EV.ExposureViewSID = EV.ExposureViewSID 
INNER JOIN [SE-SQLTO-0300].[AIRProject].[dbo].[tProject] P ON PEV.ProjectSID = P.ProjectSID 
INNER JOIN [SE-SQLTO-0300].[AIRExposure_London].[dbo].[tLocTerm] LT ON L.LocationSID = LT.LocationSID 
INNER JOIN [SE-SQLTO-0300].[AIRReference].[dbo].[tPerilSetXref] PSX ON LT.PerilSetCode = PSX.PerilSetCode 
INNER JOIN [SE-SQLTO-0300].[AIRReference].[dbo].[tPeril] PL ON PSX.PerilCode = PL.PerilCode 

WHERE P.ProjectName = 'Pricing' AND EV.ExposureViewName = 'CAP Maxed' 

GROUP BY PL.PerilCode 

是理想什么，我试图让枢的样子像这样：

 EQ  WS  SL  TC  WF  FF  ST 
B 179,166,451,986  182,394,050,346  114,374,574,342  182,394,050,346  182,394,050,346  182,394,050,346  182,394,050,346 
C 27,296,144,046  28,745,459,712  12,703,142,574  28,745,459,712  28,745,459,712  28,745,459,712  28,745,459,712 
BI  9,067,728,654 9,148,728,654 293,860,386  9,148,728,654 9,148,728,654 9,148,728,654 9,148,728,654 

Answer 1

你首先需要逆转置数据，然后再转动它：使用交叉也适用

SELECT * FROM (/*your current query here*/) t 
UNPIVOT(v FOR col IN([B],[C],[BI])) u   
PIVOT (MAX(v) FOR PerilCode IN([EQ],[WS],[SL],[TC],[WF],[FF],[ST])) p 

Answer 2

可能不是最优雅的，但这将通过使用PIVOT语法来实现。希望它有效。

;with cteTable as 
(
-- Your query here 
), cteTable2 as 
(
select PerilCode, 'B' as SecondCol, B as Value from cteTable 
union all 
select PerilCode, 'C', C from cteTable 
union all 
select PerilCode, 'BI', BI from cteTable 
) 
SELECT SecondCol, [EQ],[WS],[SL],[TC],[WF],[FF],[ST] 
FROM cteTable2 
PIVOT 
(
SUM(Value) 
FOR PerilCode IN ([EQ],[WS],[SL],[TC],[WF],[FF],[ST]) 
) AS PivotTable; 

Answer 3

我们可以实现

declare @t table (Perilcode varchar(2),B BIGINT,C BIGINT,BI BIGINT) 
insert into @t(Perilcode,B,C,BI)values ('EQ',179166451986,27296144046,9067728654), 
('WS',182394050346,28745459712,9148728654),('SL',114374574342,12703142574,293860386), 
('TC',182394050346,28745459712,9148728654),('WF',182394050346,28745459712,9148728654),('FF',182394050346,28745459712,9148728654), 
('ST',182394050346,28745459712,9148728654) 
;with CTE AS(
select col,col1,col2 from @t CROSS APPLY 
        (Select Perilcode As Col,B As Col1,'B' as Col2 UNION ALL 
        SELECT Perilcode As Col, 
        C As Col1,'C' as Col2 UNION ALL 
        SELECT Perilcode As Col, BI As Col1,'BI' as Col2 )A(col,Col1,col2) 
        GROUP BY col,Col1,col2) 


select P.col2 As Perilcode,REPLACE(CONVERT(VARCHAR,CAST([EQ]AS MONEY),1),'.00','')[EQ], 
REPLACE(CONVERT(VARCHAR,CAST([WS]AS MONEY),1),'.00','')[WS], 
REPLACE(CONVERT(VARCHAR,CAST([SL]AS MONEY),1),'.00','')[SL], 
REPLACE(CONVERT(VARCHAR,CAST([TC]AS MONEY),1),'.00','')[TC], 
REPLACE(CONVERT(VARCHAR,CAST([WF]AS MONEY),1),'.00','')[WF], 
REPLACE(CONVERT(VARCHAR,CAST([FF]AS MONEY),1),'.00','')[FF], 
REPLACE(CONVERT(VARCHAR,CAST([ST]AS MONEY),1),'.00','')[ST] from (     
Select col,col1,col2 from CTE)P 
PIVOT(MAX(Col1) FOR COL IN([EQ],[WS],[SL],[TC],[WF],[FF],[ST]))P
