Msg 46530 External data sources are not supported.

Applies to: Microsoft SQL Server 2019, Azure SQL Database

Date created: January 23, 2020.

Problem Description.

I was trying to make all the configuration required to use Polybase external tables to query an Azure SQL Database. I had installed Polybase already and proceeded to create a master key and a database credential successfully. However, when I tried to create the External Data Source the following error came up:


Msg 46530, Level 16, State 11, Line 1
External data sources are not supported with type GENERIC.




This error may appear because Polybase is installed but not configured on the instance.



Proceed to enable Polybase as shown on below image.

EXEC sp_configure 'polybase enabled', 1
