java - create object in hibernate select -

i have 2 classes:

class { b b;  public a() {} public a(b b) { setb(b); } ... }  class b { int id; public b(int id) { setid(id); } }

in hql want select this:

select new a( new b(a.b.id) ) a

but got error

org.hibernate.hql.parser - line 1:48: unexpected token: ,

is possible create object in parameter, or select field , create inside constructor?

not sure whether understood want achieve. can create hql query (with projection) query columns you're intereset in, like:

select a.whatever, b.id a join a.b b

afterwards provide implementation interface resulttransformer , set query object query.setresulttransformer(yourtransformer)

your implementation of result transformer responsible creating instances a , b
