How to use WHERE IN with Doctrine 2

问题:

I have the following code which gives me the error:

Message: Invalid parameter number: number of bound variables does not match number of tokens 

Code:

public function getCount($ids, $outcome)
{
    if (!is_array($ids)) {
        $ids = array($ids);
    }
    $qb = $this->getEntityManager()->createQueryBuilder();
    $qb->add('select', $qb->expr()->count('r.id'))
       ->add('from', '\My\Entity\Rating r');
    if ($outcome === 'wins') { 
        $qb->add('where', $qb->expr()->in('r.winner', array('?1')));
    }
    if ($outcome === 'fails') {
        $qb->add('where', $qb->expr()->in('r.loser', array('?1')));
    }
    $qb->setParameter(1, $ids);
    $query = $qb->getQuery();
    //die('q = ' . $qb);
    return $query->getSingleScalarResult();
}

Data (or $ids):

Array
(
    [0] => 566
    [1] => 569
    [2] => 571
)

DQL result:

q = SELECT COUNT(r.id) FROM \My\Entity\Rating r WHERE r.winner IN('?1')

In researching this issue, I found something that will be important to anyone running into this same issue and looking for a solution.

From the original post, the following line of code:

$qb->add('where', $qb->expr()->in('r.winner', array('?1')));

Wrapping the named parameter as an array causes the bound parameter number issue. By removing it from its array wrapping:

$qb->add('where', $qb->expr()->in('r.winner', '?1'));

This issue should be fixed. This might have been a problem in previous versions of Doctrine, but it is fixed in the most recent versions of 2.0.

回答2:

The easiest way to do that is by binding the array itself as a parameter:

$queryBuilder->andWhere('r.winner IN (:ids)')
             ->setParameter('ids', $ids);

回答3:

and for completion the string solution

$qb->andWhere('foo.field IN (:string)');
$qb->setParameter('string', array('foo', 'bar'), \Doctrine\DBAL\Connection::PARAM_STR_ARRAY);

回答4:

I found that, despite what the docs indicate, the only way to get this to work is like this:

$ids = array(...); // Array of your values
$qb->add('where', $qb->expr()->in('r.winner', $ids));

The best way doing this - especially if you're adding more than one condition - is:

$values = array(...); // array of your values
$qb->andWhere('where', $qb->expr()->in('r.winner', $values));

If your array of values contains strings, you can't use the setParameter method with an imploded string, because your quotes will be escaped!

I know the OP's example is using DQL and the query builder, but I stumbled upon this looking for how to do it from a controller or outside of the repository class, so maybe this will help others.

You can also do a WHERE IN from the controller this way:

// Symfony example
$ids    = [1, 2, 3, 4];
$repo   = $this->getDoctrine()->getRepository('AppBundle:RepoName');
$result = $repo->findBy([
    'id' => $ids
]);

This is how I used it:

->where('b.status IN (:statuses)')
->setParameters([
                'customerId' => $customerId,
                'storeId'    => $storeId,
                'statuses'   => [Status::OPEN, Status::AWAITING_APPROVAL, Status::APPROVED]
            ]);

I know it's an old post but may be helpful for someone. I would vote & enhance @Daniel Espendiller answer by addressing the question asked in comments about ints

To make this work for int's in proper way, make sure the values in array are of type int, you can type cast to int before passing...

 $qb->andWhere('foo.field IN (:ints)');
 $qb->setParameter('ints', array(1, 2), 
 \Doctrine\DBAL\Connection::PARAM_INT_ARRAY);

Tested for select/delete in symfony 3.4 & doctrine-bundle: 1.8

Found how to do it in the year of 2016: https://redbeardtechnologies.wordpress.com/2011/07/01/doctrine-2-dql-in-statement/

Quote:

Here is how to do it properly:

$em->createQuery(“SELECT users FROM Entities\User users WHERE users.id IN (:userids)”)
->setParameters(array(‘userids’ => $userIds));

The setParameters will take an array and implode it properly to be used in the “IN” statement.

I prefer:

$qb->andWhere($qb->expr()->in('t.user_role_id', [
    User::USER_ROLE_ID_ADVERTISER,
    User::USER_ROLE_ID_MANAGER,
]));

回答11:

->where($qb->expr()->in('foo.bar', ':data'))
            ->setParameter('participants', $data);

Also works with:

 ->andWhere($qb->expr()->in('foo.bar', ':users'))
                ->setParameter('data', $data);

I struggled with this same scenario where I had to do a query against an array of values.

The following worked for me:

http://docs.doctrine-project.org/projects/doctrine1/en/latest/en/manual/dql-doctrine-query-language.html#where-clause

->andWhereIn("[fieldname]", [array[]])

Array data example (worked with strings and integers):

$ids = array(1, 2, 3, 4);

Query example (Adapt to where you need it):

$q = dataTable::getInstance()
    ->createQuery()
    ->where("name = ?",'John')
    ->andWhereIn("image_id", $ids)
    ->orderBy('date_created ASC')
    ->limit(100);

$q->execute();
