Question

我试图将以下SQL代码修改为数据透视表。原始数据如下：

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

代码如下：

     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

理想情况下，我试图让枢轴看起来像是这样：

function cycleone() {
    cycleone1(document.getElementById("div1"));
}

function cycleone1(el) {
    try {
        el.disabled = el.disabled ? false : true;
    } catch (E) {}
    if (el.childNodes && el.childNodes.length > 0) {
        for (var x = 0; x < el.childNodes.length; x++) {
            cycleone1(el.childNodes[x]);
        }
    }
}

Answer 1

您需要首先取消数据的转移，然后再次转动：

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，但这可以通过使用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

使用交叉应用我们也可以实现

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

带有SUM的SQL数据透视表
