Imagine you have 2 entities that their relation is one-to-many. like cat and kitten(a cat has many kittens). now I want to load cats properties. If I use "select o.name form cat as o" I will receive an object[] of names. If I want to load kittens of cats I cant use "select o.kittens from cat as o" (imagine cat has an ArrayList property of kittens). I want to receive an object[][] of cats and thier related kittens. If I use the second query I receive "org.hibernate.QueryException: illegal syntax near collection...". what should I do to get one-to-many objects in object[][].
