The situation is like this:
I have an entity Book that holds a one-to-many relationship with Chapter.
Now if I try the query, "from Book book inner join book.chapters chapter where chapter.title like '%hibernate%'
", it gives me the desired result.
But if I try, "from Book where book.chapters.title like '%hibernate%'
", I get the error illegal attempt to dereference collection.
The thing is that I only want the collection of Book objects in return and not a collection of pair of Book and Chapter objects in return which I get with the former query.
Could someone help me understand?
