Question

I have two tables ABC, XYZ, i have taken their join on three common columns let’s say P,Q,R.

Now,

I want the response of query to be the complete joined row.

Session hibernateSession = (Session) em.getDelegate();
StringBuffer queryString = new StringBuffer();
queryString.append("SELECT t1.*, t2.* FROM ABC t1, XYZ t2 WHERE t1.P = t2.P AND t1.Q = t2.Q AND t1.R = t2.R");

Collection<----> results = query.list();

Do I need to create a new object which can store the complete join row or is there any way I can transform the result into two collections i.e. Collection<ABC> , Collection<XYZ>.

Please help me out, I am new to hibernate.

Thanks

Answer 1

you can use addEntity method on query object, like this

    session.createSQLQuery("queryString")
              .addEntity("t1")
              .addEntity("t2")
              .list();

See http://docs.jboss.org/hibernate/core/3.3/reference/en/html/querysql.html#d0e13763
