RDBMS External Data Sources are currently only supported on Azure SQL Database.

-- Elastic Database query only: a remote database on Azure SQL Database as data source   
-- (only on Azure SQL Database)  
CREATE EXTERNAL DATA SOURCE data_source_name  
    WITH (   
        TYPE = RDBMS,  
        LOCATION = '<server_name>.database.windows.net',  
        DATABASE_NAME = '<Remote_Database_Name>',  
        CREDENTIAL = <SQL_Credential>  
    )  
[;]  

See CREATE EXTERNAL DATA SOURCE

On SQL Server 2017 you can use Linked Servers
