Answer 1

我不知道[DATETIME]代表什麼，我假設它是月份或年份的指標，如果不是，您需要更改where語句以結合YEAR和MONTH。

嘗試這樣：

SELECT '2007-2008' AS FISCALYEAR, SUM(EXPENSE) AS EXPENSE 
FROM YOURTABLE 
WHERE [DATETIME] BETWEEN '4/1/2007' AND '3/31/2008' 
UNION ALL 
SELECT '2008-2009' AS FISCALYEAR, SUM(EXPENSE) AS EXPENSE 
FROM YOURTABLE 
WHERE [DATETIME] BETWEEN '4/1/2008' AND '3/31/2009' 
UNION ALL 
SELECT '2009-2010' AS FISCALYEAR, SUM(EXPENSE) AS EXPENSE 
FROM YOURTABLE 
WHERE [DATETIME] BETWEEN '4/1/2009' AND '3/31/2010' 
UNION ALL 
SELECT '2010-2011' AS FISCALYEAR, SUM(EXPENSE) AS EXPENSE 
FROM YOURTABLE 
WHERE [DATETIME] BETWEEN '4/1/2010' AND '3/31/2011' 

這應該讓你接近獲得費用每個會計年度。爲了獲得平均值，只需執行相同的操作並彙總即可。
