複数のPIVOTを使用したSQLクエリ

条件付きの集約ピボット方式として、あまり一般的ではないPIVOT演算子が導入されました。しかし、私はあなたの場合のように、一度に複数のデータ列をピボットする必要があるときにも、それが望ましいと感じています。

更新OK、あなたはUNIONとGROUPする場合は、すべてのピボットは、あなたがこの方法でそれを行うことができます結果：

注：返されたすべての列をすべてのPIVOTクエリにNull値で手動で追加する必要があるため、2つの最初のPIVOT結果を使用して作業を行っています。

, DataSrc2 as 
(
    SELECT NNumber, INumber, Issue, Tonnage, TonnageHeader, SubmittedDate, SubmittedDateHeader,Revision, RevisionHeader 
    FROM DataSrc where NNumber = 'DT1' 
) 
    , Pvt as 
    (
     SELECT NNumber,SubmittedDate1,SubmittedDate2,SubmittedDate3,SubmittedDate4, null as Issue1, null as Issue2, null as Issue3, null Issue4 
     from (select NNumber, SubmittedDateHeader, SubmittedDate from DataSrc2) src 
     PIVOT (Max([SubmittedDate]) FOR SubmittedDateHeader IN ([SubmittedDate1],[SubmittedDate2],[SubmittedDate3],[SubmittedDate4])) pv3 
     UNION ALL 
     SELECT NNumber, null as SubmittedDate1, null as SubmittedDate2, null as SubmittedDate3, null as SubmittedDate4, Issue1, Issue2, Issue3, Issue4 
     from (select NNumber, Issue, INumber from DataSrc2) src 
     PIVOT (MAX(INumber) FOR Issue in ([Issue1], [Issue2], [Issue3], [Issue4])) pv1 
) 
    select NNumber, MAX(SubmittedDate1) SD1, MAX(SubmittedDate2) SD2, MAX(SubmittedDate3) SD3, MAX(SubmittedDate4) SD4, 
        MAX(Issue1) Iss1, MAX(Issue2) Iss2, MAX(Issue3) Iss3, MAX(Issue4) Iss4 
    from Pvt 
    group by Nnumber; 

そして、これが結果ですが、私はこの仕事のために一時テーブルを構築するためにあなたをお勧めします。次のクエリは、クエリからdwgIssue派生テーブルを使用し、条件付きの集約を使用して、そこから直接結果を旋回させる

 
NNumber | SD1 | SD2     | SD3     | SD4     | Iss1 | Iss2 | Iss3 | Iss4 
:------ | :--- | :------------------ | :------------------ | :------------------ | ---: | ---: | ---: | ---: 
DT1  | null | 18/04/2017 00:00:00 | 18/04/2017 00:00:00 | 18/04/2017 00:00:00 | 1 | 3 | 2 | 2 

Warning: Null value is eliminated by an aggregate or other SET operation.
