NULL與Union

Question

已更新。

當前查詢的樣子：

SELECT MAX([Ztel]) as [Ztel] , MAX([Beztel]) as [Beztel], MAX([Otwarte]) as [Otwarte], MAX([Otwartez]) as [Otwartez], [Windykator] 
FROM (
    SELECT COUNT(C.CaseDetailsId) AS [Ztel], NULL AS [Beztel], NULL AS [Otwarte], NULL as [Otwartez], U.FirstName 
      + ' ' + U.LastName  AS [Windykator] 
    FROM CaseDetails    AS C 
      JOIN DebtorDetails  AS D 
       ON C.CaseDetailsId = D.CaseDetailsId 
      JOIN Users    AS U 
       ON C.UserId = U.UserId 
    WHERE D.DebtorDetailsId IN (SELECT DebtorDetailsId 
           FROM DebtorPhone 
           WHERE (IsValid = 'True') 
             OR (IsDefault = 'True')) 
      AND C.CaseStatusId <> 2 
      AND C.CaseStatusId <> 6 
    GROUP BY 
      U.FirstName, U.LastName 
    UNION ALL 
    SELECT NULL, COUNT(CaseDetailsId), NULL, NULL, U.FirstName + ' ' + U.LastName AS [Windykator] 
    FROM CaseDetails AS C 
      JOIN Users AS U 
       ON C.UserId = U.UserId 
    WHERE C.CaseStatusId <> 2 
      AND C.CaseStatusId <> 6 
    GROUP BY 
      U.FirstName, U.LastName 
    UNION ALL 
    SELECT NULL, NULL, COUNT(CaseDetailsId), NULL, U.FirstName + ' ' + U.LastName AS [Windykator] 
    FROM CaseDetails AS C 
      JOIN Users AS U 
       ON C.UserId = U.UserId 
    WHERE C.CaseStatusId = 1 
    GROUP BY 
      U.FirstName, U.LastName 
    UNION ALL 
    SELECT NULL, NULL, NULL, COUNT(C.CaseDetailsId), U.FirstName 
      + ' ' + U.LastName  AS [Windykator] 
    FROM CaseDetails    AS C 
      JOIN DebtorDetails  AS D 
       ON C.CaseDetailsId = D.CaseDetailsId 
      JOIN Users    AS U 
       ON C.UserId = U.UserId 
    WHERE D.DebtorDetailsId IN (SELECT DebtorDetailsId 
           FROM DebtorPhone 
           WHERE (IsValid = 'True') 
             OR (IsDefault = 'True')) 
      AND C.CaseStatusId = 1 
    GROUP BY 
      U.FirstName, U.LastName 
    ) AS x 
GROUP BY [Windykator] 

做工精細但他們要我增加額外的3列到數據集。從CaseDetailsView列取得：ClientNameShort，SetId，EndServiceDate。想法？或者我應該做另一個子查詢？

預期的結果：使用 http://oi43.tinypic.com/2vdi5vk.jpg

表：

CaseDetailsView：SETID，ClientNameShort，用戶ID，EndServiceDate，CaseDetailsId，CaseStatusId - 案例整體名單
DebtorDetails：CaseDetailsId，DebtorDetailsId - 債務人細節
DebtorPhone：DebtorDetailsId - 債務人電話號碼列表。

欄3：總體病例數，其中CaseStatusId <> 2和<> 6
Column4：總體病例數，其中CaseStatusId <> 2和<> 6和存在於DebtorPhone（在這裏我們得到了手機的情況下，這樣的數數債務人）
Column5：開放病例數（其中CaseStatusId = 1）整體
Column6：開放病例數（其中CaseStatusId = 1）和DebtorPhone存在（所以我們有電話號碼的債務人）

如果你只想在一行中顯示所有內容，你可以試試這個

SELECT MAX([Ztel]), MAX([Beztel]), MAX([Windykator]) 
FROM (
     ..... 
    ) AS x 

UPDATE：

基礎上您的意見，我想你正在尋找的是這個

SELECT MAX([Ztel]), MAX([Beztel]), [Windykator] 
FROM (
    SELECT COUNT(C.CaseDetailsId) AS [Ztel], NULL AS [Beztel], U.FirstName 
      + ' ' + U.LastName  AS [Windykator] 
    FROM CaseDetails    AS C 
      JOIN DebtorDetails  AS D 
       ON C.CaseDetailsId = D.CaseDetailsId 
      JOIN Users    AS U 
       ON C.UserId = U.UserId 
    WHERE D.DebtorDetailsId IN (SELECT DebtorDetailsId 
           FROM DebtorPhone 
           WHERE (IsValid = 'True') 
             OR (IsDefault = 'True')) 
      AND C.CaseStatusId <> 2 
      AND C.CaseStatusId <> 6 
    GROUP BY 
      U.FirstName, U.LastName 
    UNION ALL 
    SELECT NULL, COUNT(CaseDetailsId), U.FirstName + ' ' + U.LastName AS [Windykator] 
    FROM CaseDetails AS C 
      JOIN Users AS U 
       ON C.UserId = U.UserId 
    WHERE C.CaseStatusId <> 2 
      AND C.CaseStatusId <> 6 
    GROUP BY 
      U.FirstName, U.LastName 
    ) AS x 
GROUP BY [Windykator]
