SELECT DISTINCT p FROM Player p, IN (p.teams) t WHERE t.league.sport = :sport
Data retrieved: The players who participate in the specified sport.
Description: The sport persistent field belongs to the League entity. To reach the sport field, the query must first navigate from the Player entity to Team (p.teams) and then from Team to the League entity (t.league). Because the league relationship field is not a collection, it can be followed by the sport persistent field.
