ssas - 有没有办法将数据从 SSAS 维度表示转换回关系表示？

Question

我在徘徊，如果有办法将 SSAS OLAP 多维数据集逆向工程回其原始关系表示。这样的事情可能吗？

Answer 1

我能够在我的 Sql Server 上设置一个链接服务器，然后使用 OpenQuery 来获取数据。它有点难看，但你可以像下面这样：

SELECT "[Dimension Name].[Hierarchy Name].[Department Name].[MEMBER_CAPTION]" as Department,
  round("[Measures].[Some Calculation]",3) as Value,
  'Value_Descr' as Value_Descr
FROM OPENQUERY(SSAS_Link,' SELECT NON EMPTY { [Measures].[Some Calculation] } ON COLUMNS
    ,NON EMPTY {([Date Dimension].[Hierarchy].[Fiscal Year Code].ALLMEMBERS * [Dimension Name].[Hierarchy Name].[Lowest Hierarchy Level Field].ALLMEMBERS) } DIMENSION PROPERTIES MEMBER_CAPTION
    ,MEMBER_UNIQUE_NAME ON ROWS FROM (
    SELECT ({ [Dimension Name].[Field to Filter].& [Key of Field to filer] }) ON COLUMNS
    FROM (SELECT ([Fiscal Week Code - Last Week]) ON COLUMNS FROM [Cube Name])  )
    WHERE ([Dimension Name].[Field to Filter].& [Key of Field to filer]) ')
