Hitta frågetabeller och lista objekt relaterade till externa dataanslutningar

Ibland behöver du ta reda på frågetabeller och lista objekt relaterade till någon extern dataanslutning. Frågetabeller är relaterade till objekt för extern dataanslutning med anslutnings-ID, medan lista objekt är relaterade till en frågetabell.
