I don't have the access to mount that storage location to my other workspace. As it is a driver, I assumed doing this was not the right option. When the driver sends fetch requests after query completion, Databricks generates and returns presigned URLs to the uploaded files. To allow pyodbc to switch connections to a different SQL warehouse, add an entry to the [ODBC Data Sources] section and a matching entry below [SQL_Warehouse] with the specific connection details. In the below code, we will first create the JDBC URL, which contains information like SQL Server, SQL Database name on Azure, along with other details like Port number, user, and password. If you have versioning enabled, you can still enable Cloud Fetch by following the instructions in Advanced configurations. Create a file named pyodbc-test-cluster.py with the following content.
