Oracle Cross database queries: you need a “database link” for that

Posted by jpluimers on 2016/09/27

I recently learned that you can do cross database queries in Oracle using database links.

You need to prefix your objects with the right schema/owner (for instance dbo.) and suffix with an @ sign followed by the database link name.

This query finds all configured database links:

select * from all_db_links;
