Symfony 1.4 select query with selected columns is not working

Question

I want to run following query in symfony doctrine.

SELECT p.id AS id FROM skiChaletPrice p WHERE ski_chalet_id = ? AND month = ?

I wrote my doctrine query as following.

 $q = Doctrine_Query::create()
                ->select('p.id AS id')
                ->from('skiChaletPrice p')
                ->andWhere('ski_chalet_id = ?', $chaletId)
                ->andWhere('month = ?', $from);      

 $result = $q->fetchOne();
 if ($result->count() > 0) {            
     return $result->toArray();
 } else {
     return null;
 }   

But my result always include all columns in the table. What the issue? Please help me.

Answer 1

The issue is that fetchOne() will return a Doctrine object, which implicitly contains all the columns in the table. $result->toArray() is converting that doctrine object to an array, which is why you get all the columns.

If you only want a subset of column, don't hydrate an object, instead do something like this:

$q = Doctrine_Query::create()
            ->select('p.id AS id')
            ->from('skiChaletPrice p')
            ->andWhere('ski_chalet_id = ?', $chaletId)
            ->andWhere('month = ?', $from);  

$results = $q->execute(array(), Doctrine::HYDRATE_SCALAR);
