插入的與CTE查詢結果到一個臨時表

Question

我想把這個查詢的結果存儲到一個臨時表：

WITH cOldest AS 
(
    SELECT 
     *, 
     ROW_NUMBER() OVER (PARTITION BY [MyKey] ORDER BY SomeColumn DESC) AS rnDOB 
    FROM MyTable 
) 
SELECT 
    C.* 
*** Insert into #MyTempTable *** This part doesn't work 
    FROM 
    cOldest C 
    WHERE 
    C.rnDOB = 1 

在此先感謝。

假設這是SQL服務器：熱膨脹係數是好的只有一個聲明 - 所以你不能同時擁有SELECT和INSERT - 只使用INSERT：

WITH cOldest AS 
(
    SELECT 
     *, 
     ROW_NUMBER() OVER (PARTITION BY [MyKey] ORDER BY SomeColumn DESC) AS rnDOB 
    FROM MyTable 
) 
INSERT INTO #MyTempTable(Col1, Col2, ....., ColN) 
    SELECT Col1, Col2, ...., ColN 
    FROM cOldest C 
    WHERE C.rnDOB = 1 

這就要求#MyTempTable已經存在。如果要用SELECT創建它 - 請使用以下語法：

WITH cOldest AS 
(
..... 
) 
SELECT c.* 
INTO #MyTempTable 
FROM cOldest c 
WHERE C.rnDOB = 1
