Question

我有一个返回的UNIONed查询：

ReceiptFolderID FolderParentID FolderTypeID FolderType                                         FolderName                                         FolderDescription                                  ReceiptCount
--------------- -------------- ------------ -------------------------------------------------- -------------------------------------------------- -------------------------------------------------- ------------
3               0              1            Pending Receipts                                   Pending Receipts                                   System folder; user cannot delete                  1
7               0              2            Uncategorized Receipts                             Uncategorized Receipts                             System folder; user cannot delete                  2
26              8              3            User-Defined Folder                                European Travel                                    Folders created by users                           0
25              0              3            User-Defined Folder                                Family Receipts                                    Folders created by users                           0



SELECT ReceiptFolderID, FolderParentID, tbl_ReceiptFolders.FolderTypeID, 
        FolderType,
         CASE tbl_ReceiptFolderTypes.FolderTypeID 
             WHEN 1 THEN tbl_ReceiptFolderTypes.FolderType 
             WHEN 2 THEN tbl_ReceiptFolderTypes.FolderType 
             ELSE tbl_ReceiptFolders.FolderName 
         END AS FolderName, 
        tbl_ReceiptFolderTypes.FolderDescription,
        dbo.GetFolderReceiptCount(ReceiptFolderID) AS ReceiptCount
INTO #tmp_UserFolders           
FROM tbl_ReceiptFolders LEFT JOIN tbl_ReceiptFolderTypes ON tbl_ReceiptFolders.FolderTypeID=tbl_ReceiptFolderTypes.FolderTypeID
WHERE UserID=@UserID 
AND (tbl_ReceiptFolderTypes.FolderTypeID = 1 
     OR tbl_ReceiptFolderTypes.FolderTypeID = 2)
--ORDER BY tbl_ReceiptFolderTypes.FolderTypeID ASC

UNION

SELECT ReceiptFolderID, FolderParentID, tbl_ReceiptFolders.FolderTypeID, 
        FolderType,
         CASE tbl_ReceiptFolderTypes.FolderTypeID 
             WHEN 1 THEN tbl_ReceiptFolderTypes.FolderType 
             WHEN 2 THEN tbl_ReceiptFolderTypes.FolderType 
             ELSE tbl_ReceiptFolders.FolderName 
         END AS FolderName, 
        tbl_ReceiptFolderTypes.FolderDescription,
        dbo.GetFolderReceiptCount(ReceiptFolderID) AS ReceiptCount
INTO #tmp_UserFolders
FROM tbl_ReceiptFolders LEFT JOIN tbl_ReceiptFolderTypes ON tbl_ReceiptFolders.FolderTypeID=tbl_ReceiptFolderTypes.FolderTypeID
WHERE UserID=@UserID 
AND (tbl_ReceiptFolderTypes.FolderTypeID <> 1 
     OR tbl_ReceiptFolderTypes.FolderTypeID <> 2)

正如您所看到的，Pending和Uncategorized Receipts将始终首先显示，其余的按字母顺序排列。

现在，把它扔进SPROC，这是我用#temp文件夹做的事情不起作用。

通过什么方法让sproc返回这些结果？

谢谢！

Answer 1

在第二个查询中，您有

(tbl_ReceiptFolderTypes.FolderTypeID <> 1          
 OR tbl_ReceiptFolderTypes.FolderTypeID <> 2)

好吧，想一想......每条记录都会满足这个谓词。无论FolderTypeID的值是多少，它都不是1，或者不是2。

如果我理解你想要的东西，试试这个：

Select ReceiptFolderID, FolderParentID,
    f.FolderTypeID, FolderType,
  Case t.FolderTypeID 
    When 1 Then t.FolderType
    When 2 Then t.FolderType                          
    Else f.FolderName End FolderName,   
  t.FolderDescription,
  dbo.GetFolderReceiptCount(ReceiptFolderID) ReceiptCount    
From tbl_ReceiptFolders f
   Left Join tbl_ReceiptFolderTypes t
       On f.FolderTypeID = t.FolderTypeID
Where UserID = @UserID 
Order By Case When t.FolderTypeID In (1,2) 
           Then 0 Else 1 End

编辑添加Count（）试试这个：

Select ReceiptFolderID, FolderParentID,
    f.FolderTypeID, FolderType,
  Case t.FolderTypeID 
    When 1 Then t.FolderType
    When 2 Then t.FolderType                          
    Else f.FolderName End FolderName,   
  t.FolderDescription,
  Count(h.ReceiptFolderID) ReceiptCount    
From tbl_ReceiptFolders f
   Left Join tbl_ReceiptFolderTypes t
       On f.FolderTypeID = t.FolderTypeID
   Left Join tbl_ReceiptFolderLnk h 
       On h.ReceiptFolderID = f.ReceiptFolderID
Where UserID = @UserID
Group By ReceiptFolderID, FolderParentID,
    f.FolderTypeID, FolderType, t.FolderDescription,
  Case t.FolderTypeID 
    When 1 Then t.FolderType
    When 2 Then t.FolderType                          
    Else f.FolderName End,          
  Case When t.FolderTypeID In (1,2) 
    Then 0 Else 1 End
Order By Case When t.FolderTypeID In (1,2) 
           Then 0 Else 1 End

SPROC按字母顺序排列结果，除了前两个结果？
