計算所有12個月的GrandTotal

Question

行中我有一到十二個月的時間。

我有三欄：Year,Month和查詢總數。

我想在底部添加一行來計算總計查詢：

SELECT 
YEAR(date) AS [Year], 
MONTH(date) AS [Month], 
COUNT(*) 
from EnquiryMaster 
Group By YEAR(date), MONTH(date) 

Answer 1

你或許應該，而顯示在用戶界面層的總數，但如果你真的想從SQL做到這一點服務器，你可以嘗試像

SELECT YEAR(date) AS [Year], 
     MONTH(date) AS [Month], 
     COUNT(*) 
from EnquiryMaster 
Group By YEAR(date), 
      MONTH(date) 
UNION ALL 
SELECT YEAR(date) AS [Year], 
     NULL, 
     COUNT(*) 
from EnquiryMaster 
Group By YEAR(date) 

而且，也許看看Summarizing Data Using ROLLUP

Answer 2

 SELECT YEAR(date) AS [Year], 
      MONTH(date) AS [Month], 
      COUNT(*) 
    from EnquiryMaster 
    Group By YEAR(date), MONTH(date) 

在此查詢中，您將獲得特定年份的每個月的12條記錄，因爲您正在執行GROUP BY年和月，如果您只想要一年的一條記錄，則必須從查詢中刪除MONTH（日期）。

查詢會是這樣： -

 SELECT YEAR(date) AS [Year], 
      MONTH(date) AS [Month], 
      COUNT(*) 
    from EnquiryMaster 
    Group By YEAR 

Answer 3

嘗試 「WITH ROLLUP」 SQL的設施。

SELECT YEAR(date), 
MONTH(date), 
count(*) as data_nums 
FROM EnquiryMaster 
GROUP BY YEAR(date),MONTH(date) WITH ROLLUP 

希望這將有助於你
