Question

我有一到十二个月的行。

我有三列：Year，Month和总查询次数。

我想在底部添加一行来计算总查询次数：

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

Answer 1

尝试使用“WITH ROLLUP”sql的工具。

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

希望这会对你有所帮助

Answer 2

您可能更应该在UI层中显示总计，但如果您真的希望从SQL Server执行此操作，则可以尝试类似

的内容

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)

另外，请查看Summarizing Data Using ROLLUP

Answer 3

     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月12条记录，因为您正在进行GROUP BY年和月，如果您只需要一年的一条记录，则必须从查询中删除MONTH（日期）。

查询将如下： -

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

计算所有12个月的总计
