如何在教义 2 中使用 WHERE IN
2022-08-30 06:49:23
						我有以下代码给我错误:
Message: Invalid parameter number: number of bound variables does not match number of tokens 
法典:
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 $query->getSingleScalarResult();
}
数据(或$ids):
Array
(
    [0] => 566
    [1] => 569
    [2] => 571
)
DQL 结果:
q = SELECT COUNT(r.id) FROM \My\Entity\Rating r WHERE r.winner IN('?1')
