Use Limit and Offset in Doctrine2 query

Question

I'm trying to do the pagination, but there is an error:

[Syntax Error] line 0, col 57: Error: Expected end of string, got 'limit'

I'm not quite sure if this is the right syntax (and logic) to make my query:

public function getFriendsFromTo ($user, $limit, $offset)
{
     return $this->getEntityManager()
        ->createQuery('SELECT f FROM EMMyFriendsBundle:Friend f WHERE f.user='.$user.' limit '.$limit. 'offset' .$offset)
        ->getResult();
}

Friends and users are related manyToOne and oneToMany, so in the friends table there is a field - user_id.

This is in my controller:

$user = $this->get('security.context')->getToken()->getUser();
$id = $user->getId();

$friends = $user->getFriends();
$result = count($friends)
$FR_PER_PAGE = 7;
$pages = $result/$FR_PER_PAGE;

$em = $this->getDoctrine()->getEntityManager();
$friends = $em->getRepository('EMMyFriendsBundle:Friend')
         ->getFriendsFromTo($id, $FR_PER_PAGE, $page*$FR_PER_PAGE); 

I know that it's stupid and even wrong (especially the third parameter to be $page*$FR_PER_PAGE), but I just wanted to try if the query works, and it didn't.

Answer 1

Nope. Use:

  return $this->getEntityManager()
        ->createQuery('...')
        ->setMaxResults(5)
        ->setFirstResult(10)
        ->getResult();

Answer 2

$towary = $this->getDoctrine()
   ->getRepository('AcmeStoreBundle:Towar') 
   ->findBy(array(),array(),10,($current-1)*$numItemsPerPage);

Answer 3

You can use findBy 3rd and 4th parameters of method of doctrine repository, which are limit and offset.

Here is the method definition:

findBy(
    array        $criteria,
    array        $orderBy  = null, 
    integer|null $limit    = null,
    integer|null $offset   = null
)

Answer 4

you can also use

$query->getSingleResult();
