我有3代表的註冊，修訂，問題，我需要通過發行ID的降序排列最新的4期，版本ID我已經成功做了查詢，如下所示，SQL樞紐和功能

SELECT 
[DrawingID], 
[RevisionID], 
[IssueID], 
Number, 
[Revision], 
[Issue Number],   
       'Issue' + Cast(rn AS CHAR(10)) AS Issue 
     FROM (
SELECT dwgReg.Number, 
dwgRev.Revision, 
dwgIssue.[Issue Number], 
dwgReg.ID as DrawingID, 
dwgRev.ID as RevisionID, 
dwgIssue.ID as IssueID,        
         Row_number() 
         OVER ( 
          partition BY dwgIssue.[Drawing ID] 
          ORDER BY dwgReg.[ID], dwgRev.[Revision] 
         DESC, dwgIssue.[Issue Number] DESC) 
           AS rn 
       FROM Issue dwgIssue 
         INNER JOIN Register dwgReg 
           ON dwgIssue.[Drawing ID]=dwgReg.ID 
         INNER JOIN Revision dwgRev 
           ON dwgRev.ID=dwgIssue.[Revision ID] 
            AND dwgRev.[Drawing ID]=dwgReg.ID)dwgIssue 
            where rn<=4

我只需要轉動此查詢與SQL函數的幫助，其結果需要像，

DrawingID數Issue1 Issue2 Issue3 Issue4

每個繪圖將有最大的4排，最少1排。請有人幫我一個查詢。

我只是使用條件聚合。以下是針對問題所應採取的措施：

select i.drawingid, 
     max(case when seqnum = 1 then id end) as issueid_1, 
     max(case when seqnum = 2 then id end) as issueid_2, 
     max(case when seqnum = 3 then id end) as issueid_3, 
     max(case when seqnum = 4 then id end) as issueid_4 
from (select i.*, 
      row_number() over (partition by i.drawingid order by i.revisionid desc) as seqnum 
     from issue i 
    ) i 
group by i.drawingid;

剩下的只是加入所需的其他列。

@VickySelvam。。。將其用作子查詢或CTE，然後加入它。 –

我附加的查詢工作完全正常，是否有可能透視並將該查詢轉換爲函數 –

使用TESTDB GO

WITH CTE

 AS (SELECT [Drawing ID] , 
        MAX(CASE WHEN IssueCount = 1 THEN ID 
         END) AS Issue_1 , 
        MAX(CASE WHEN IssueCount = 2 THEN ID  
         END) AS Issue_2 , 
        MAX(CASE WHEN IssueCount = 3 THEN ID 
         END) AS issue_3 , 
        MAX(CASE WHEN IssueCount = 4 THEN ID 
         END) AS issue_4 
      FROM  (SELECT ID , 
           ProjectID , 
           [Drawing ID] , 
           [Revision ID] , 
           [Issue Number] , 
           ROW_NUMBER() OVER (PARTITION BY [Drawing ID] ORDER BY [Revision ID] DESC) AS IssueCount 
         FROM  dbo.ISSUE (NOLOCK) 
        ) i 
      GROUP BY [Drawing ID] 
     ) 
SELECT [Drawing ID] , 
     Issue_1 , 
     Issue_2 , 
     issue_3 , 
     issue_4 
FROM CTE
