Question

我正在尝试在Gridview中进行列式添加但不能。

就像我从商店程序中填充gridview，它提供了这些值。

DateTime 10Quantity 20Quantity 30Quantity 10Amount 20Amount 30Amount GrandTotal
03/10/2015  792      0           594        7920        0     17820   25740
03/10/2015  332      3           194        9990        0     28220   38739

预期：

DateTime 10Quantity 20Quantity 30Quantity 10Amount 20Amount 30Amount GrandTotal
03/10/2015  792      0           594        7920        0     17820   25740
03/10/2015  332      3           194        9990        0     28220   38739
Totals      1124     3           788        17910       0     46040   64479

我想要一个新的行'Totals'，它应代表每列的总数，即添加。

代码：

SP;

            select  Convert(varchar(20),serverdatetime,101) 'DateTime',amount,1 'Quantity'
                 from tickets
                 WHERE CONVERT(DATE,ServerDateTime) BETWEEN @FromDate and @ToDate
        )
        select *, 10 * c.[10Quantity] '10Amount',20 * c.[20Quantity] '20Amount',30 * c.[30Quantity] '30Amount',((10 * c.[10Quantity])+(20 * c.[20Quantity])+(30 * c.[30Quantity]))'GrandTotal' from (
        SELECT DateTime,[10] AS '10Quantity', [20] AS '20Quantity', [30] AS '30Quantity'
        FROM 
        (SELECT [DateTime], amount,quantity
        FROM myquery) p
        PIVOT
        (
        COUNT ([Quantity])
        FOR [Amount] IN
        ( [10], [20], [30])
        ) AS pvt
        ) as c
    END

我必须从前端进行，即gridview

Answer 1

使用RowDataBound事件处理程序在将数据添加到GridView时评估数据（总和列）。

添加页脚以显示总数。

看看这个： https://msdn.microsoft.com/en-us/library/bb310552.aspx 第3步：解决方案2。这就是你使用事件处理程序在GridView中运行总计的方法。

Answer 2

实际上，您可以使用SUM在sql本身找到每列的GROUPING SETS。

<强>查询

SELECT [DateTime],
SUM([10Quantity]) AS [10Quantity],
SUM([20Quantity]) AS [20Quantity],
SUM([30Quantity]) AS [30Quantity],
SUM([10Amount]) AS [10Amount],
SUM([20Amount]) AS [20Amount],
SUM([30Amount]) AS [30Amount],
SUM([GrandTotal]) AS [GrandTotal]
FROM table_name
GROUP BY 
GROUPING SETS(([DateTime],[10Quantity],[20Quantity],
[30Quantity],[10Amount],[20Amount],[30Amount],[GrandTotal]),());

如何在sql中生成每列的总和？
