Ich habe folgendes Schemata:

A - one to many - B
B - one to many - C

Wie kann ich eine H. Query bauen die mir nur Daten aus A zurückliefert, wenn es in C zu B welche gibt. Also so was in SQL:

select c.id from category as c where c.id in (select cat_id from tournament as t inner join wette as w on t.id like w.tournament_id )
