以月历格式创建报告以在日期的每一列中显示数据

Question

我想创建一个报告，我将在其中显示每个月每天在我的网站上注册用户的数量。

我正在使用 ASP.NET 4.5 和 C# 进行后端编码。我正在从数据库中获取数据以计算使用 SQL Server 2008 的每日注册用户数。

这是我的存储过程，我从表中检索每日注册用户的数据。

select  tb.Month, 
        tb.day, 
        COUNT(tb.Month) as Total 
from (
    select  intId, 
            MONTH(dtRegDate) as Months, 
            datename(month, dtRegDate) as Month, 
            DATENAME(DAY, dtRegDate) as day
    from tblUserDetails
    ) tb
group by tb.Month, tb.day, Months
order by tb.Months

现在我想以表格格式显示此结果数据，如下图所示。

请帮助我。提前致谢。

我猜你想数intID 而不是Month。您可以使用旋转：

;WITH cte AS (
select  tb.[Months],
        tb.[Month], 
        tb.[Day], 
        COUNT(tb.intId) as [Total]
from (
        select  intId, 
                MONTH(dtRegDate) as [Months],
                datename(month, dtRegDate) as [Month], 
                DATENAME(DAY, dtRegDate) as [Day]
        from tblUserDetails
    ) tb
group by tb.Month, tb.day, Months
)

SELECT *
FROM cte
PIVOT (
    SUM([Total]) FOR [Day] IN ([1],[2],[3]...)
) pvt
order by [Months]
