爲什麼在SQL Server中使用ROW_NUMBER時會出現錯誤？

Question

我寫了下面的SQL代碼在我的SQL Server上運行。

SELECT 
    atd.DeviceID, 
    ROW_NUMBER() over(order by atd.deviceid) as rownumber 
FROM 
    dbo.Devices atd 
WHERE 
    (rownumber between 11 and 20); 

我得到以下輸出：

Msg 207, Level 16, State 1, Line 5
Invalid column name 'rownumber'.
Msg 207, Level 16, State 1, Line 5
Invalid column name 'rownumber'.

正如你所看到的，我想用ROW_NUMBER只得到通常會由查詢返回的行的子集。我從來沒有使用過ROW_NUMBER函數。

我在做什麼錯？

不能直接使用列的別名，把它包裝上派生表或CTE：

SELECT * 
FROM ( SELECT DeviceID, 
     ROW_NUMBER() over(order by deviceid) as rownumber 
     FROM dbo.Devices) atd 
WHERE (rownumber between 11 and 20); 

或者

;WITH CTE AS 
(
    SELECT DeviceID, 
    ROW_NUMBER() over(order by deviceid) as rownumber 
    FROM dbo.Devices 
) 
SELECT * 
FROM CTE 
WHERE (rownumber between 11 and 20);
