Question

我在SQL Server中的存储过程中有以下SQL代码，它将数据提供给报表。现在我们正在实现SSAS多维数据集来处理数据。我有一个事实表，其中包含所有度量和退化维度。我们在将低于计算转换为MDX时遇到问题。此计算完全取决于“开始日期”和“结束日期”参数，因此无法在ETL时间完成。当客户在报告上选择开始日期和结束日期时，必须执行此操作。

任何人都可以帮助/指导我如何将下面的代码转换为MDX吗？作为MDX世界的新手，我面临以下问题

一个。缺少像结构这样的临时表，有助于在处理过程中存储临时数据。

湾CLR或COM对象支持存储过程。为什么缺少SQL / MDX过程？

是否可以从多维数据集数据执行以下计算？

    rundate ,Entity ,MasterEntity   ,TransactionDate    ,BuyOrSell  ,Quantity2  ,Quantity1  ,Quantity3  ,Quantity4  ,Profit1
