Question

这可能是一个愚蠢的问题，但SQL不是我的强项。

我有一些已经聚合的数据，我用它来显示为饼图，并根据ASPxDashBoardViewer上的参数向下钻取。我的问题是，有时数据可能会显示一些值为0％的图表项，然后无法点击。

存储过程返回的表如下所示：

DECLARE @Responses TABLE
(
    Code varchar(10),
    Description varchar(255),
    [Status Code Count] int,
    [Month] varchar(255),
    [Category] varchar(255)
)

我复制了以下数据的示例。可能有多个具有相同类别和不同状态代码计数的项目，我在饼图中使用此值，状态代码计数值（Sum）以及类别，代码和描述的参数。这样可以从类别开始向下钻取饼图。（当您深入查看某个类别时，您会看到构成该类别的所有代码/说明。）

所以我想做的是，在不改变主要过程的情况下，这是非常不稳定的，是改变选择聚合数据的最终选择语句。我想排除状态代码总和的任何内容，对于具有相同类别的所有行，如果该类别的总和状态代码计数的百分比，总计数将产生一个百分比，当转换时将舍入为零到int。

proc结束时的select语句如下所示：

SELECT 
    Code, Description, SUM([Status Code Count]) AS [Status Code Count], 
    [Month], Category 
FROM @Responses 
GROUP BY code, [Description], [Month], Category

数据如下所示：

Answer 1

SELECT 
    Code, Description, SUM([Status Code Count]) AS [Status Code Count], 
    [Month], a.Category 
FROM @Responses a
JOIN (SELECT Category, SUM([Status Code Count]) AS Total FROM @Responses GROUP BY Category) b ON a.Category = b.Category
GROUP BY code, [Description], [Month], a.Category
HAVING CONVERT(INT, 100 * SUM([Status Code Count]) / Total) >= 1

Answer 2

尽管我愿意接受CrimsonKing的回答，但它并没有给我我期望的结果。（我会尝试修改它以使其工作，然后如果可以的话接受它。它比这简单得多......）

这是我的解决方案，但有点难看。

将表格定义更改为：

DECLARE @Responses TABLE
(
    Code varchar(10),
    Description varchar(255),
    [Status Code Count] int,
    [Month] varchar(255),
    [Category] varchar(255),
    Percentage float
)

然后使用像这样的游标而不是最后的选择：

DECLARE @Count float
SELECT @Count = SUM([Status Code Count]) from @Responses
DECLARE @Category varchar(255) 
DECLARE totals_cursor CURSOR FOR 
SELECT Category FROM @Responses

OPEN totals_cursor

FETCH NEXT FROM totals_cursor INTO @Category

WHILE @@FETCH_STATUS = 0
BEGIN
    DECLARE @Percentage float 
    SELECT @Percentage=SUM([Status Code Count])/@Count*100 FROM @Responses WHERE Category = @Category
    UPDATE @Responses SET Percentage = @Percentage WHERE Category = @Category
    FETCH NEXT FROM totals_cursor INTO @Category
END

CLOSE totals_cursor;
DEALLOCATE totals_cursor;

SELECT Code, Description, SUM([Status Code Count]) AS [Status Code Count], [Month], Category
FROM @Responses
WHERE CAST(percentage as int) > 0
GROUP BY code, [Description], [Month], Category

MS SQL SUM一个字段基于另一个字段的值，并排除低于N百分比的值
