Dotaz na spojení dvou tabulek

Pokud FK v Posts.*_Airport_code neodkazuje na Airports.id jak MJB předpokládá, ale na Airports.Airport_code pak

SELECT
  APS.Airport_name AS Source,
  APD.Airport_name AS Destination,
  Posts.date_of_departure
FROM Posts
  INNER JOIN Airports APS ON(APS.Airport_code = Posts.Source_Airport_code)
  INNER JOIN Airports APD ON(APD.Airport_code = Posts.Destination_airport_code)
