什麼是選擇當前月的最佳途徑日期在SQL Server 2008 R2

Question

可能重複：
Get a list of dates between two dates using a function

我需要得到的結果作爲

1/01/2011 
2/01/2011 
3/01/2011 
4/01/2011 
5/01/2011 
. 
. 
. 
31/01/2011 

我不想爲此創建一個表。只是想得到這個結果。

Answer 1

試試這個：

DECLARE @startDate DATETIME; 
    SET @startDate = CAST(DATEPART(YYYY,GETDATE()) AS VARCHAR(4)) + CAST(DATEPART(M,GETDATE()) AS VARCHAR(2)) + '01'; 

    ;WITH CTE(n) AS 
    (SELECT 0 UNION ALL SELECT n+1 FROM CTE WHERE n < 30) 
    SELECT DATEADD(dd,n,@startDate) 
    FROM CTE 
    WHERE MONTH(DATEADD(dd,n,@startDate)) = MONTH(@startDate);
