Doctrine2 - relationship - doctrine-orm

Question

I'm developing an application, which is looking for optimal route and timetable in public transport. I have some experience about Doctrine1, but it's my first time with Doctrine2. There is soem new fields to describe relations (mappedBy and inversedBy) and also some new ways of mapping.
I have following code:
$query = $this->em->createQuery("SELECT partial cls.{stop}, partial t.{arriveTime, departureTime} FROM \Entities\Timetable t
JOIN t.ride r
JOIN t.carrierLineStop cls
WHERE t.departureTime>=:time AND
r.idCarrierLine=:carrierLine AND
(cls.idStop=:firstStop OR cls.idStop=:lastStop)");
$query->setParameters(array(
'time' => $time,
'carrierLine' => $path->getLine(),
'firstStop' => $path->getFirstStop(),
'lastStop' => $path->getLastStop()
));
When I try to execute that script I've got an error:
[Semantical Error] line 0, col 24 near '}, partial t.{arriveTime,': Error: There is no mapped field named 'stop' on class Entities\CarrierLineStop.
Mapping files:
Entities\CarrierLineStop:
type: entity
table: carrier_line_stop
fields:
idCarrierLineStop:
id: true
type: integer
unsigned: false
nullable: false
column: id_carrier_line_stop
generator:
strategy: IDENTITY
nextStop:

unsigned: false
nullable: true
column: next_stop
manyToOne:
idCarrierLine:

I have no idea about where the problem is...

Answer 1

I think that the keyword partial works only on entity fields (like idCarrierLineStop and nextStop), stop is a composite field.
If you want to leave the query like this you should delete the ManyToOne mapping and add a field mapping with id_stop or alternatively add a JOIN with the Stop entity in the query and return its id in place of cls.{stop}
