Cross Database Querying
Enable elastic query for SQL DW - this would allow cross database query in SQL DataWarehouse.
Thanks for the suggestion. We are looking into this scenario for a future release. 7558005
Team, let us know on when can we expect this feature?
When a PaaS Sql Database is added to the same server where a SQL Data Warehouse is located, allow three part table references and eliminate the need to create data sources and external tables. For data security, use AAD integrated and leverage existing security constructs. This should allow security to be set in one place and allow cross database queries that use the actual end user account. Then End User query activity would be captured in Audit tables.
This would take away a lot of headache

This feature is a blocker to all traditional DW environments to move to Azure SQL DW as most of datawarehouse design will use multi sourcesystems in their ETL staging DB. Please can you let us know when this is expected to be released to Azure SQL DW?

Hopefully this includes the USE <database> statement too.

While I am commenting without yet knowing the intended database design, we have found multiple analytic scenarios that need to couple more than one data transaction/fact domain with another such as Invoice data domain with Inventory data domain
