爲未知列數動態創建列

Question

我希望完成的是在存儲過程中根據需要動態創建列。我的問題在於，一個驅動可能沒有激勵，1個激勵或多個（2,3,4.etc）激勵分配給驅動。下面的屏幕截圖例如數據：

我最初使用FOR XML路徑來連接記錄：

Stuff ((Select ', ' + isnull(EM.Description,'') 
    From EquipmentMaster EM 
     Inner Join EquipmentDetail ED On EM.EquipmentID = ED.EquipmentID And EM.EquipmentType=3 
     Where ED.DriveID = DM.DriveID 
      For XML PATH(''), TYPE).value('.', 'varchar(max)') 
      ,1, 2, '') as [Incentives] 

但最終用戶所要求的激勵機制是在單獨的列。我正在嘗試重新使用我在此處找到的一些代碼：Stack Overflow link

但是我無法使其工作。希望得到一些幫助，使這個過程的工作。

下面是程序代碼：

declare 
@startDate datetime, 
@endDate datetime, 
@RegID varchar(8000), 
@OrgID varchar(8000), 
@SubID varchar(8000), 
@COID varchar(8000), 
@RecID varchar(8000), 
@StatusID varchar(8000), 
@Cols nvarchar(max), 
@Incentives nvarchar(max) 

Select @Cols = Stuff ((Select ', ' + isnull(EM.Description,'') 
      From EquipmentMaster EM 
      Inner Join EquipmentDetail ED On EM.EquipmentID = ED.EquipmentID And EM.EquipmentType=3 
      --Where ED.DriveID = DM.DriveID 
      For XML PATH(''), TYPE).value('.', 'varchar(max)') 
      ,1, 2, '') 

Select 
DM.DriveID [DriveID], 
DM.FromDateTime [FromDateTime], 
Case When DM.OwnerType = 0 Then Acct.Name Else CD.DescLong End As [OwnerName], 

Stuff ((Select ', ' + isnull(EM.Description,'') 
    From EquipmentMaster EM 
     Inner Join EquipmentDetail ED On EM.EquipmentID = ED.EquipmentID And EM.EquipmentType=3 
     Where ED.DriveID = DM.DriveID 
      For XML PATH(''), TYPE).value('.', 'varchar(max)') 
      ,1, 2, '') as [Incentives] 
From 
rpt_DriveMaster DM 
Left Outer Join rpt_Accounts Acct on DM.AccountID=Acct.AccountID 
Left Outer Join IDViewRecruiters Rec on Acct.RecruiterID=Rec.CodeID 
Inner Join rpt_CenterDetail CD on DM.CenterID=CD.CenterID 

Where 
DM.StatusID <>5 
And DM.FromDateTime Between '03/01/2015' AND '03/02/2015' 

這是我的作品帶給所有激勵成一列（和使用SSRS顯示報表）原程序：

Create Procedure Hema_IncentiveReport

@endDate datetime, 
@RegID varchar(8000),

Answer 1

我將該表重新創建爲矩陣，並在「驅動器ID」字段中創建一個行分組。然後我在激勵字段上創建了一個列組，並將其值設置爲： =IIF(IsNothing(Fields!Incentive.Value),True,False)
