我是DAX和SSAS-Tabular的新手,所以我希望你能原谅任何无知。
我们有一个SSAS-Tabular多维数据集,我们在Excel中使用它来查看数据(数据透视表)。有没有办法让我在Excel中查看度量背后的DAX?
谢谢,
利

在Excel中,转到“数据”选项卡,单击“新建查询”,选择“从数据库”,从“SQL Server Analysis Services数据库”中选择“。” 输入服务器的名称和数据库的名称(多维数据集的名称) 单击“MDX或DAX查询(可选)”旁边的下拉列表 添加以下查询(请注意,这是DMX,而不是MDX或DAX,但它可以工作 - 请注意,如果您不编辑目录名称以匹配您的多维数据集,它将不会返回任何数据):
SELECT
[MEASUREGROUP_NAME] AS [Table Name],
[MEASURE_CAPTION] AS [Measure Name],
[DESCRIPTION] AS [Measure Description],
[EXPRESSION] AS [Measure Logic]
FROM
$SYSTEM.MDSCHEMA_MEASURES
WHERE
[CUBE_NAME] ='Model'
AND
[MEASURE_IS_VISIBLE]
AND
[CATALOG_NAME] = '<enter name of your cube here>'
ORDER BY
[MEASUREGROUP_NAME]
点击“加载”。
您现在在电子表格中有一个页面,用作度量的数据字典。你可以做同样的事情,用这段代码添加维度的查询:
SELECT
[DIMENSION_UNIQUE_NAME] AS [Table Name],
HIERARCHY_CAPTION AS [Column Name],
[DESCRIPTION] AS [Column Description]
FROM
$system.MDSchema_hierarchies
WHERE
[CUBE_NAME] = 'Model'
AND
[HIERARCHY_ORIGIN] = 2
AND
[HIERARCHY_IS_VISIBLE]
AND
[CATALOG_NAME] = '<enter name of your cube here>'
ORDER BY
[DIMENSION_UNIQUE_NAME]
对于表格,此代码:
SELECT
[DIMENSION_CAPTION] AS [Table Name],
[DESCRIPTION] AS [Table Description]
FROM
$system.MDSchema_Dimensions
WHERE
[CUBE_NAME] ='Model'
AND
[DIMENSION_CAPTION] <> 'Measures'
AND
[CATALOG_NAME] = '<enter name of your cube here>'
ORDER BY
[DIMENSION_CAPTION]
对于层次结构,此代码:
SELECT
[DIMENSION_UNIQUE_NAME] AS [Table Name],
[HIERARCHY_CAPTION] AS [Hierarchy Name],
[DESCRIPTION] AS [Hierarchy Description]
FROM
$system.MDSchema_hierarchies
WHERE
[CUBE_NAME] = 'Model'
AND
[HIERARCHY_ORIGIN] = 1
AND
[CATALOG_NAME] = '<enter name of your cube here>'
ORDER BY
[DIMENSION_UNIQUE_NAME]
如果编辑这些查询的属性(使用数据选项卡上的“连接”按钮),则可以在每次打开工作表时将此工作表设置为刷新(类似于您可能已设置数据透视表连接的方式) ),现在您拥有自动反映最新立方体设计的数据字典选项卡。希望这有帮助!
