Question

我试图只获得每个文件ID的一次出现和最后一次，即我提供的方式，即使我提供了一个FileID，它仍会返回多个。

SELECT  
            FM.FileNumber, FA.ReceivedDate AS LienSearchOrderDate, 
            FA1.ReceivedDate AS LienSearchReceivedDate, 
            DATEDIFF(dd, FA.ReceivedDate, FA1.ReceivedDate) AS TurnTimeDaysLienSearch, 
            FM.FileID, PC.Name, C.County, P.State, S.Name AS Status, 
            FM.ClientsFileNumber
FROM        dbo.FileMain AS FM 
INNER JOIN  dbo.FilePartnerRel AS FPR ON FM.FileID = FPR.FileID AND FPR.PartnerTypeID = 10011 
INNER JOIN  dbo.PartnerCompany AS PC  ON FPR.PartnerCompanyID = PC.PartnerCompanyID 
LEFT JOIN   dbo.FileActions AS FA     ON FM.FileID = FA.FileID 
LEFT JOIN   dbo.FileActions AS FA1    ON FA.FileID = FA1.FileID 
LEFT JOIN   dbo.ActionDef AS AD       ON FA1.ActionDefID = AD.ActionDefID 
INNER JOIN  dbo.Property AS P         ON FA1.FileID = P.FileID 
INNER JOIN  dbo.County AS C           ON P.CountyID = C.CountyID 
INNER JOIN  dbo.Status AS S           ON FM.StatusID = S.StatusID
WHERE FM.FileNumber = 'PA-22440' 
  and (FM.OpenedDate > '2012-10-01') 
  AND (FA.ActionDefID = 28) 
  AND (FA.ReceivedDate IS NOT NULL) 
  AND (FA.Live = 1) AND (FA1.ActionDefID = 183) 
  AND (FA1.Live = 1)
Group by FA.ReceivedDate, FM.FileNumber, FA1.ReceivedDate, FM.FileID, PC.Name, C.County, 
         P.State, S.Name, FM.ClientsFileNumber
Order by 1

我确信我有一些过度使用查询，但我在这里尝试。我可以得到它以获得最低限度的发生，但我想让它拉出每个实例FileNumber。

以下是我得到的输出：

FileNumber  LienSearchOrderDate LienSearchReceivedDate  TurnTimeDaysLienSearch  FileID  Name    County  State   Status  ClientsFileNumber
PA-22440    38:37.6 NULL    NULL    16448   NTIS    Pinellas    FL  Cancelled   test
PA-22440    40:08.8 NULL    NULL    16448   NTIS    Pinellas    FL  Cancelled   test

，预期只是最后一项，仅此而已。

尝试此查询，如果它是您需要的

SELECT      FM.FileNumber, FA.ReceivedDate AS LienSearchOrderDate, 
            FA1.ReceivedDate AS LienSearchReceivedDate, 
            DATEDIFF(dd, FA.ReceivedDate, FA1.ReceivedDate) AS TurnTimeDaysLienSearch, 
            FM.FileID, PC.Name, C.County, P.State, S.Name AS Status, 
            FM.ClientsFileNumber
FROM        dbo.FileMain AS FM 
INNER JOIN  dbo.FilePartnerRel AS FPR ON FM.FileID = FPR.FileID AND FPR.PartnerTypeID = 10011 
INNER JOIN  dbo.PartnerCompany AS PC  ON FPR.PartnerCompanyID = PC.PartnerCompanyID 
LEFT JOIN   dbo.FileActions AS FA     ON FM.FileID = FA.FileID 
LEFT JOIN   dbo.FileActions AS FA1    ON FA.FileID = FA1.FileID 
LEFT JOIN   dbo.ActionDef AS AD       ON FA1.ActionDefID = AD.ActionDefID 
INNER JOIN  dbo.Property AS P         ON FA1.FileID = P.FileID 
INNER JOIN  dbo.County AS C           ON P.CountyID = C.CountyID 
INNER JOIN  dbo.Status AS S           ON FM.StatusID = S.StatusID
WHERE FM.FileNumber = 'PA-22440' 
  and (FM.OpenedDate > '2012-10-01') 
  AND (FA.ActionDefID = 28) 
  AND (FA.ReceivedDate IS NOT NULL) 
  AND (FA.Live = 1) AND (FA1.ActionDefID = 183) 
  AND (FA1.Live = 1)
  AND (FA.ReceivedDate = (SELECT MAX(ReceivedDate) FROM FileActions WHERE ActionDefID = 28 AND ReceivedDate IS NOT NULL AND Live = 1 AND FileID = FM.FileID))
Order by FM.FileNumber

如果您在FileActions表中有一个主键，我希望您拥有该主键，请使用它来匹配正确的记录，而不是将其与ReleaseDate匹配。像这样：

AND FA.PrimaryKey = (SELECT TOP 1 PrimaryKey FROM FileActions WHERE FileID = FM.FileID ORDER BY ReleaseDate DESC)

在SQL中拉出文件编号的最后一次出现
