Pyspark notebook : Lakehouse Sql end point
- 1 year ago
Hi msprog,
A Fabric PySpark notebook can’t “see” T-SQL views that live in a Lakehouse’s SQL analytics endpoint via the Spark catalog. Those views are objects of the SQL endpoint (TDS/T-SQL world), not Spark. But you can query them from a notebook by connecting to the SQL endpoint (via JDBC/TDS or the built-in Fabric Spark TDS reader). Alternatively, re-create the logic as a Spark view/table if you want native Spark access.
Query the view from a notebook
Get your Workspace ID and the SQL endpoint name (Lakehouse’s SQL endpoint).
In the notebook, use the Fabric Spark TDS reader (Scala cell) to run a T-SQL query and bring the result back as a Spark DataFrame.
// Scala cell import com.microsoft.spark.fabric.tds.implicits.read.FabricSparkTDSImplicits._ import com.microsoft.spark.fabric.Constants val wsId = "<your-workspace-guid>" val lakehouseSqlEndpointName = "<your-lakehouse-sql-endpoint-name>" // Query the view val df = spark.read .option(Constants.WorkspaceId, wsId) .option(Constants.DatabaseName, lakehouseSqlEndpointName) .synapsesql("select * from dbo.YourViewName"); display(df)Notes:
This uses the built-in Fabric Spark TDS integration outlined in community write-ups like this walkthrough: https://www.red-gate.com/simple-talk/blogs/fabric-query-a-sql-endpoint-from-a-notebook/
If your query is complex and you hit parser quirks, the same article shows a prepareQuery pattern to send part of the query “as-is”.
If you found this helpful, consider giving some Kudos. If I answered your question or solved your problem, mark this post as the solution
thanks for this. but i want to invoke a view that is defined - i can see the view when i am on the sql endpoint. Hence i was hoping if the notebook can see the endpoint, i would be able to fire a query using the view.
