计算所有12个月的GrandTotal

Question

行中我有一到十二个月的时间。

我有三栏：Year,Month和查询总数。

我想在底部添加一行来计算总计查询：

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

Answer 1

你或许应该，而显示在用户界面层的总数，但如果你真的想从SQL做到这一点服务器，你可以尝试像

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)

Answer 2

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

在此查询中，您将获得特定年份的每个月的12条记录，因为您正在执行GROUP BY年和月，如果您只想要一年的一条记录，则必须从查询中删除MONTH（日期）。

查询会是这样： -

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

Answer 3

尝试 “WITH ROLLUP” SQL的设施。

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

希望这将有助于你
