i encountered a problem, when using a left join command in a query.
Basically, what happened is that my joined results were not appearing
in the final results of the query. After carefully testing the
validity of the actual query (by testing the query to mysql directly)
i realized that the problem can not originate from mysql as such.

A few details:

Model A:
Consists of an (primary key) 'id' of type string, length 16
and a few other fields, most importantly for this example a field
'code' (string/10)

Model B:
Has a field 'mandantPath' that is related to model A (field id)
through a hasOne() relation.

#code
$this->hasOne('mandant_db_node as mandant', array
('local'=>'mandantPath','foreign'=>'id'));

#here is my query

        $l=Doctrine_Query::create()
                         ->select('*,p.code')
                         ->from('contact_db_customer cc')
                         ->leftJoin('cc.mandant p')
                         ->where($w)
                         ->offset($request['startindex']+0)
                         ->limit($request['rows']+0)
                         ->orderBy($order)
                         ->execute(array());

Now, if i call this the way i do (above), i get the basic results
(fields), but not the joined ones. If i get the SQL query generated by
Doctrine, and use it directly, it works just fine and it returns the
'code' field as it should.

However, when i add type Doctrine::HYDRATE_ARRAY to the execute
command, i get the correct results, but of course encapsuled.. so that
i have to loop/parse through the result and set the values according
to my demands.

Pretty frustrating - while i am certain that the problem is very basic
and i just lack the knowledge of a proper solution. Hopefully someone
in here knows what i am dealing with - specifically, what it is that i
am doing wrong.
