symfony querybuilder query need to write - symfony

Question

I have the following tables in mysql with given relationships and same has been define in the symfony2. I want to achieve the following query which I wrote it down below. can some one help me how can I write it in querybuilder?
unitids(id,unitid,databaseid)
Mappaths(id,ref_unitid2(forigen key for unitids id) ,ref_unitid1 (forigen key for unitids id),nomal value)
traveltime(id,ref_map_path(forigen key for mappaths id), traveltime,noobjs,ondate)
my mysql query is like this :
SELECT t.ID,t.ondate, un.databaseid as source1,
un1.databaseid as desitnation, t.traveltime, t.noobjs
FROM test.traveltime t
left join test.mappaths p on t.ref_map_path = p.ID
left join test.unitids un on (p.ref_unitids1 = un.id )
left join test.unitids un1 on (p.ref_unitids2= un1.id)
where un.databaseid=50 and un1.databaseid =1 limit 1;
which give me each one row of source and destination of and objects etc like this :
in symfony2 when i run this query
$query = $em->createQueryBuilder();
$results = $query->select('un.databaseid,un1.databaseid')
->from('ApiMapBundle:Traveltime', 't')
->leftJoin('t.refMapPath', 'p')
->leftJoin('p.refUnitids2', 'un')
->leftJoin('p.refUnitids1', 'un1')
->where('un.databaseid = :bdatabaseid1')
->setParameter('bdatabaseid1', 2)
->andwhere('un1.databaseid = :bdatabaseid2')
->setParameter('bdatabaseid2',1)
//->setMaxResults(1)
->getQuery()
->getResult();
it give me output like
Array ( [0] => Array ( [databaseid] => 1 ) [1] => Array ( [databaseid] => 1 ))
but instead it should give me
Array ( [0] => Array ( [databaseid] => 1 ) [1] => Array ( [databaseid] => 2 ))
How can i achieved this above output?????

Assumed that you are writing code in Repository and you also defined relations in your Entities
$em = $this->getEntityManager();
$query = $em->getRepository('BUNDLE:traveltime')->createQueryBuilder('t');
$query->select('t.Id,..')
->leftJoin('t.ref_map_path','p')
->leftJoin('p.ref_unitids1','un')
->leftJoin('p.ref_unitids2','un1')
->where('un.databaseid = :bdatabaseid')
->setParameter('bdatabaseid',1)
->orWhere('un1.databaseid = :bdatabaseid1')
->setParameter('bdatabaseid1',2);
