Question

我正在尝试编写一个查询，为表格的每一行添加名称。看起来它应该很简单但我无法理解，因为我不是SQL的专家。

这就是我希望我的桌子看起来像：

         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

现在是我的表：

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

这是它背后的查询（我正在使用SQL Server Management Studio）：

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]

我正在考虑添加一个包含行计数的列，并以某种方式将行数从数字更改为名称，但我不知道该怎么做。任何帮助，将不胜感激。感谢。

只需为每个选择添加“文本字符串”，如下所示：

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]

SQL表 - 每行命名
