SQL Server中的選擇最重要的關系不會返回預期的數據

Question

我有一個名為NdtReports的表， NdtReports包含以下數據：

另一個名為ndtreportdetails表包含此數據：

這兩個表基於ndtreportdetails.reportid和Report.id

我執行此查詢：

SELECT TOP 1 WITH TIES 
    NRD.NdtType, NRD.RequestNumber, NR.NdtReportNumber,
    NRD.ResponseReportDatetime, NRD.Defect,
    NRD.ResponseReportNumber, NRD.Remark
FROM   
    dbo.NdtReportDetails NRD
LEFT OUTER JOIN 
    NdtReports NR ON NRD.ReportId = NR.Id
WHERE  
    NRD.JointId = 1661632
    AND NRD.NdtType IN ('RT', 'PT', 'PWHT', 'MT', 'UT')
ORDER BY 
    NRD.Id DESC

它返回以下結果：

它返回最大id的關節ID的最后記錄，但是對於所有RT,PT,UT類型RT,PT,UT我都需要最大ID的最后記錄。 預期結果應為ID為139189（PT），139139（UT），139192（RT）的3條記錄
