SQL Server：查找ReportServer目录报表参数和参数的数据集

Question

我正在寻找SSRS报告参数以及用于分类报告的每个参数的数据集。我的目标是通过提示名称和提供该参数值的数据集找到每个参数。有了这些信息，我将在asp.net项目中构建一组动态控件，以允许用户使用他们选择的参数来创建自己的订阅。我知道那里的信息，但我不知道如何通过SSMS到达。下面的代码显示了我尝试过的内容，并提供了相关信息，但是我无法将2链接在一起。

julia> reduce(+, [2 3 4], init = 1)
10

julia> reduce((accumulator, value) -> push!(accumulator, value^2), [1, 2, 3], init = [])
3-element Array{Any,1}:

    -- XMLifyies Catalog's Content column.
    /* For report (Type = 2) and shared data source (Type = 5) objects, the image-typed column

    SELECT *,

    /* Table DataSource contains a row for each data source (embedded or shared) used in each report.

SELECT * FROM Data

我想要提示的参数名称和用于创建可用值的数据集。因此，我想在其中记录SSSS Promp Param =“ Customers”的一列标记为数据集的列，该列沿“ Select * fromcustomers”的行显示，如果那是分配给该SSRS参数的数据集
