カウントを使用して出現を決定し、データを連結する

Question

CR.DestinationDepotのレコードが2つあるかどうかを調べるために、今すぐ連結する方法とは対照的に（例えば）KNI/KHNのように連結します。何か案は？ありがとうございました。

select CR.DestinationCountry, 
mm.MovementRef, 
CR.DestinationDepot, 
case when count(CR.DestinationDepot) >= 2 then 'yes' else 'no' end as [statement], 
Case when (CR.DestinationCountry <> 'GB') and count(CR.DestinationDepot) >= 2 then CR.DestinationDepot+'/'+CR.DestinationDepot else CR.DestinationDepot end as [DestinationDepot] 
FROM dbo.MALExport AS ME 
    INNER JOIN dbo.movConLink AS MCL ON ME.ConsignmentReference = MCL.ConsignmentReference 
    INNER JOIN dbo.cgtRoute AS CR ON CR.RouteID = MCL.CMRRouteID 
    INNER JOIN dbo.movMovement AS MM ON MM.MovementRef = ME.MovementReference 
    group by cr.DestinationCountry, cr.DestinationDepot, mm.MovementRef

次のコードは、あなたが

select CR.DestinationCountry, 
mm.MovementRef, 
CR.DestinationDepot, 
case when count(CR.DestinationDepot) >= 2 then 'yes' else 'no' end as [statement], 
Case when (CR.DestinationCountry <> 'GB') and count(CR.DestinationDepot) >= 2 then CR.DestinationDepot+'/'+CR.DestinationDepot else CR.DestinationDepot end as [DestinationDepot] 
,stuff((SELECT '/' + CR2.DestinationDepot' ' FROM dbo.cgtRout cr2 
    WHERE CR.DestinationCountry <> 'GB' and CR2.RouteID = MCL.CMRRouteID order by CR2.RouteID desc FOR XML PATH('')),1,1,'') AS [DestinationDepot2] 
FROM dbo.MALExport AS ME 
    INNER JOIN dbo.movConLink AS MCL ON ME.ConsignmentReference = MCL.ConsignmentReference 
    INNER JOIN dbo.cgtRoute AS CR ON CR.RouteID = MCL.CMRRouteID 
    INNER JOIN dbo.movMovement AS MM ON MM.MovementRef = ME.MovementReference 
    group by cr.DestinationCountry, cr.DestinationDepot, mm.MovementRef
