SQL表 - 每行的名稱

Question

我想寫一個查詢，爲我的表的每一行添加名稱。它似乎應該很簡單，但我不能弄明白，因爲我不是SQL的專家。

這裏就是我想我的表看起來像：

  New Cancels Net 
Daily  0   1 -1 
Weekly 0  1 -1 
Monthly 25 34 -9 
Quarterly 25 34 -9 
Annually 535 552 -17 
Total  3418 1398 2020 

這裏是我的表現：

New  Cancels Net 
0   1 -1 
0   1 -1 
25   34 -9 
25   34 -9 
535   552 -17 
3418 1398 2020 

下面是它背後的查詢（我使用SQL Server Management Studio中）：

SELECT [New Orders] 
     ,[Cancels] 
     ,[Net] 
FROM [DailyFigures] 
WHERE [UID] IN (
SELECT TOP 1 [UID] 
FROM [DailyFigures] 
ORDER BY [UID] DESC) 
UNION ALL 
SELECT [Orders] 
     ,[Cancels] 
     ,[Net] 
FROM [WeeklyFigures] 
WHERE [UID] IN (
SELECT TOP 1 [UID] 
FROM [WeeklyFigures] 
ORDER BY [UID] DESC) 
UNION ALL 
SELECT [Orders] 
     ,[Cancels] 
     ,[Net] 
FROM [MonthlyFigures] 
WHERE [UID] IN (
SELECT TOP 1 [UID] 
FROM [MonthlyFigures] 
ORDER BY [UID] DESC) 
UNION ALL 
SELECT [Orders] 
     ,[Cancels] 
     ,[Net] 
FROM [QuarterlyFigures] 
WHERE [UID] IN (
SELECT TOP 1 [UID] 
FROM [QuarterlyFigures] 
ORDER BY [UID] DESC) 
UNION ALL 
SELECT [Orders] 
     ,[Cancels] 
     ,[Net] 
FROM [AnnuallyFigures] 
WHERE [UID] IN (
SELECT TOP 1 [UID] 
FROM [AnnuallyFigures] 
ORDER BY [UID] DESC) 
UNION ALL 
SELECT SUM([Orders]) AS Orders, SUM([Cancels]) AS Cancels, SUM([Net]) AS Net FROM [AnnuallyFigures] 

我正在考慮添加一個列的行數，並以某種方式從數字更改行數名稱，但我不知道如何做到這一點。任何幫助，將不勝感激。謝謝。

只需添加一個「文本字符串」爲每個單獨的選擇是這樣的：

SELECT 'DAILY' as ' ', [New Orders],[Cancels],[Net] 
FROM [DailyFigures] 
WHERE [UID] IN 
    (SELECT TOP 1 [UID] FROM [DailyFigures] ORDER BY [UID] DESC) 

UNION ALL 

SELECT 'WEEKLY' as ' ', [Orders],[Cancels],[Net] 
FROM [WeeklyFigures] 
WHERE [UID] IN 
    (SELECT TOP 1 [UID] FROM [WeeklyFigures] ORDER BY [UID] DESC) 

UNION ALL 

SELECT 'MONTHLY' as ' ', [Orders],[Cancels],[Net] 
FROM [MonthlyFigures] 
WHERE [UID] IN 
    (SELECT TOP 1 [UID] FROM [MonthlyFigures] ORDER BY [UID] DESC) 

UNION ALL 

SELECT 'QUARTERLY' as ' ', [Orders],[Cancels],[Net] 
FROM [QuarterlyFigures] 
WHERE [UID] IN 
    (SELECT TOP 1 [UID] FROM [QuarterlyFigures] ORDER BY [UID] DESC) 

UNION ALL 

SELECT 'ANNUALLY' as ' ', [Orders],[Cancels],[Net] 
FROM [AnnuallyFigures] 
WHERE [UID] IN 
    (SELECT TOP 1 [UID] FROM [AnnuallyFigures] ORDER BY [UID] DESC) 

UNION ALL 

SELECT 'TOTAL' as ' ', 
    SUM([Orders]) AS Orders, 
    SUM([Cancels]) AS Cancels, 
    SUM([Net]) AS Net 
FROM [AnnuallyFigures]
