我需要一个查询，每个图纸将返回一行，最新的4个问题按照RevID（修订表）的desc分组，然后通过ISsue ID（问题表）进行描述，需要为每个图纸选择前4个记录四个记录与枢轴一起组合，如
DNo | ISsue1 | Issue2 | Issue3 | Issue4 | SDate1 | SDate2 | SDate3 | Sdate4 | EDate1 | EDate2 | EDate3 | EDate4 | Total1 | Total2 | Total3 | Total4
我尝试了以下内容，
CREATE FUNCTION [dbo].[Dwg_logQuery_Test](@ProjectID int)

但我失败多次PIVOT 所以请一些人帮我解决这个问题。
先谢谢。

好的，如果您想要UNION和GROUP所有透视结果，您可以这样做：
注意：我已经完成了两个第一个PIVOT结果的工作，因为您必须手动将所有返回的列与空值一起添加到所有PIVOT查询。
, 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;
这就是结果，但我建议你为这份工作建立一个临时表。
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.

以下查询使用查询中的dwgIssue派生表，并使用条件聚合直接从中调整结果：
SELECT
ID,
Number,
Issue1 = MAX(CASE rn WHEN 1 THEN [Issue Number] END),
Issue2 = MAX(CASE rn WHEN 2 THEN [Issue Number] END),
Issue3 = MAX(CASE rn WHEN 3 THEN [Issue Number] END),
Issue4 = MAX(CASE rn WHEN 4 THEN [Issue Number] END),
Tonnage1 = MAX(CASE rn WHEN 1 THEN Tonnage END),
Tonnage2 = MAX(CASE rn WHEN 2 THEN Tonnage END),
Tonnage3 = MAX(CASE rn WHEN 3 THEN Tonnage END),
Tonnage4 = MAX(CASE rn WHEN 4 THEN Tonnage END),
SubmittedDate1 = MAX(CASE rn WHEN 1 THEN SubmittedDate END),
SubmittedDate2 = MAX(CASE rn WHEN 2 THEN SubmittedDate END),
SubmittedDate3 = MAX(CASE rn WHEN 3 THEN SubmittedDate END),
SubmittedDate4 = MAX(CASE rn WHEN 4 THEN SubmittedDate END),
EORReturnDate1 = MAX(CASE rn WHEN 1 THEN EORReturnDate END),
EORReturnDate2 = MAX(CASE rn WHEN 2 THEN EORReturnDate END),
EORReturnDate3 = MAX(CASE rn WHEN 3 THEN EORReturnDate END),
EORReturnDate4 = MAX(CASE rn WHEN 4 THEN EORReturnDate END),
Revision1 = MAX(CASE rn WHEN 1 THEN Revision END),
Revision2 = MAX(CASE rn WHEN 2 THEN Revision END),
Revision3 = MAX(CASE rn WHEN 3 THEN Revision END),
Revision4 = MAX(CASE rn WHEN 4 THEN Revision END)
FROM
(
SELECT
dwgReg.ID,
dwgIssue.[Issue Number],
rn = ROW_NUMBER() OVER (PARTITION BY dwgIssue.[Drawing ID]
ORDER BY dwgReg.[ID], dwgRev.[Revision] DESC, dwgIssue.[Issue Number] DESC),
dwgRev.Revision,
Tonnage = isnull(dwgIssue.weight1,0)+isnull(dwgIssue.weight2,0)+isnull(dwgIssue.weight3,0),
SubmittedDate = dwgRev.[SDate],
EORReturnDate = dwgRev.[EDate],
dwgReg.Number
FROM
dbo.Issue AS dwgIssue
INNER JOIN Register AS dwgReg
ON dwgIssue.[Drawing ID] = dwgReg.ID

WHERE dwgReg.ProjectID=@ProjectID
) AS dwgIssue

;
在引入PIVOT运算符之后，条件聚合可能不太常见，因为它是一种旋转方法。但是，当我需要同时转动多个数据列时，我仍然觉得它更合适，就像你的情况一样。
