如何在沒有任何自定義表的情況下迭代最近六個月（包括當前）循環？

Question

我想輸出一樣如下：

目前我使用的表。但我不想在任何表格（除了系統表格）中使用它。可能嗎？

查詢（使用表）：

DECLARE @End_date DATETIME 
SET @End_Date = DATEADD(month, -6, GETDATE()) 

SELECT DISTINCT MONTH(S.ACDATE) AS Mon,CONVERT(CHAR(4),S.ACDATE) AS Month_Name, 
    (YEAR(S.ACDATE) % 100) AS Year_No 
    FROM SALES as S 
    WHERE S.ACDATE < DATEADD(month,MONTH(getdate()), 
      DATEADD(year,YEAR(getdate())-1900,0)) 
    AND S.ACDATE >= DATEADD(month,MONTH(@End_Date)-1, 
     DATEADD(year,YEAR(@End_Date)-1900,0)) 

Answer 1

DECLARE @dt DATE = CONVERT(DATE, '05/03/2013', 101) 

SELECT MONTH (dt) AS Mon, LEFT (DATENAME (mm, dt), 3) AS Month_Name, YEAR (dt) % 1000 AS Year_No 
FROM (
    SELECT DATEADD (mm, -diff, @dt) dt 
    FROM (VALUES(1),(2),(3),(4),(5),(6))t(diff) 
) t 

結果集是：

Mon   Month_Name Year_No
