ignore where statement if parameter is null in doctrine - sql

Question

Hi i have a problem in QueryByilder in Doctrine. i wrote a Query that has 2 parameter and they affect in where statement. i want to ignore where statement if the related parameter was null. for example if $play = 3 and $theater = null the query must return all tickets with play 3 and whatever theater
this is my code:
public function getAllSearchedTickets($play,$teater){
return $this->getEntityManager()->createQuery('
select s from mtadminBundle:ReserveLocation s
join s.reserve a
join a.sance b
where a.acceptCode != 0
and b.play = :play
and b.teater = :teater')
->setParameters(array('play'=>$play,'teater'=>$teater))->getResult();
}
thank you.

You should use the QueryBuilder for this, to do it more efficiently, I'll show you how you do yours and then the same with the QueryBuilder as example:
Yours:
public function getAllSearchedTickets($play,$teater){
$query = 'select s from mtadminBundle:ReserveLocation s'.
'join s.reserve a'.
'join a.sance b'.
'where a.acceptCode != 0');
$paramArray = array();
if( $play ) {
$query .= ' and b.play = :play';
$paramArray['play'] = $play;
}
if( $teater ) {
$query .= ' and b.teater = :teater';
$paramArray['teater '] = $teater;
}
return $this->getEntityManager()->createQuery($query)
->setParameters($paramArray)->getResult();
}
QueryBuilder:
public function getAllSearchedTickets($play,$teater){
$queryBuilder = $this->getEntityManager()->createQueryBuilder();
$queryBuilder->select('s')
->from('mtadminBundle:ReserveLocation', 's')
->join('s.reserve', 'a')
->join('a.sance', 'b')
->where('a.acceptCode != 0');
if( $play ) {
$queryBuilder->andWhere('b.play = :play');
$queryBuilder->setParameter('play', $play);
}
if( $teater ) {
$queryBuilder->andWhere('b.teater = :teater');
$queryBuilder->setParameter('teater', $teater);
}
return $queryBuilder->getResult();
}
