我正在寻找 SSRS 报告参数和用于编目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来查找每个参数。有了这些信息，我将在一个 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创建自己的订阅。我知道信息在那里，但我不知道如何通过 SSMS 访问它。下面的代码显示了我尝试过的内容并为我提供了信息，但我无法将两者链接在一起。

我想要提示的参数名称和用于创建可用值的数据集。所以像 SSRS Promp Param = "Customers" 我想在该记录中有一个标记为数据集的列，该列显示类似于“Select * from customers”的内容如果这是分配给该 SSRS 参数的数据集
