Question

I need tune query for performance. The tree of objects like:

classA {
 classB b;
 classC c;
.....}

I need select similar to SQL:

select a.field1, b.field2, c.field3, c.field4 from a left outer join b 
  on a.id=b.fk left outer join c on b.id=c.fk

I don’t understand what kind of result will be returned, does it arrayList? Or query returns
all 3 objects?
Thanks.

Answer 1

It will be

List<Object[]> list = new ArrayList<Object[]>();
