如何使用SUM，GROUP BY函數獲取累積數據

Question

我請求你原諒這麼冗長的查詢，但我迫切需要幫助。 當我運行下面的查詢時，我得到每日數據。但我希望每月的數據，使用LASTDAY， SUM，GROUP BY功能。 例如，如果我在＃startDt＃中選擇「20130501」，在＃endDt＃中選擇「20130701」，則應該給我3行累計結果;五月，六月和七月。誰能幫忙？

，你可以這樣做

SELECT DATENAME(MONTH , DAY) , SUM(COLUMN1) , SUM(COLUMN2) .. 
FROM (YOURQUERY) AS A 
GROUP BY DATENAME(MONTH , DAY) 

我認爲這會幫助你。
