Dax Studio - Python Connection

mithunt — Mon, 06 Oct 2025 09:57:35 GMT

Hello All,

There is a plan to move data source from one database to another for which it would be essential for us to understand the dashboards within a workspace.

I have explored few options in Dax Studio which has capability to return Measures, Columns, Catalogs (Dashboards) and other details of a specific workspace.

However if I need to get a detailed inforamtion across all the Power BI Dashboards in a workspace, the commands below would not allow me to.

SELECT [CATALOG_NAME] FROM $SYSTEM.DBSCHEMA_CATALOGS
SELECT [CATALOG_NAME] FROM $SYSTEM.DBSCHEMA_CATALOGS,
SELECT [ID],[Name] FROM $SYSTEM.TMSCHEMA_TABLES WHERE NOT [IsHidden]
SELECT * FROM $SYSTEM.TMSCHEMA_COLUMNS WHERE NOT [IsHidden]
SELECT [ID],[TableID],[Name],[QueryDefinition] FROM $SYSTEM.TMSCHEMA_PARTITIONS
SELECT [ID],[TableID],[Name],[Expression] FROM $SYSTEM.TMSCHEMA_MEASURES WHERE NOT [IsHidden]
SELECT * FROM $SYSTEM.TMSCHEMA_RELATIONSHIPS

Requesting your guidance if there is a way I can loop through all the commands above and get the data into Excel format or into SQL or connect to Power BI directly so that I can analyze it further.

Regards

Mithun T

Hi mithunt,

You’re on the right track using the $SYSTEM DMVs. The trick is to (1) enumerate every dataset (catalog) in the workspace, then (2) loop your DMV queries against each catalog, and (3) export to CSV/Excel or land it in SQL for analysis.

– If you just need files fast: Use DAX Studio’s command-line to loop a workspace and export DMV results to CSV/XLSX or straight to SQL. It’s simple and robust. Docs, output modes.
– If you want code & full control: Use Python + XMLA (e.g., pyadomd/python-tabular) to connect to each dataset and run your DMV statements, then write to Excel/SQL.
– If you want full workspace inventory (reports, dashboards, lineages, permissions): Use the Power BI Admin Scanner APIs to pull metadata for all artifacts in one shot, then optionally enrich with DMV details via XMLA. Admin – WorkspaceInfo, Scanner quickstart.

Note: Querying XMLA endpoints (DMVs/TOM) requires the workspace to run on Premium/Fabric capacity (or PPU). XMLA endpoint overview, Premium features.

If you found this helpful, consider giving some Kudos. If I answered your question or solved your problem, mark this post as the solution.
