How to use WHERE IN with Doctrine 2

Question

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

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

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.

and for completion the string solution

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

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));

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
