我有以下引发异常的代码Invalid parameter number: number of bound variables does not match number of tokens。然而，当我打印注册参数时，我的参数出现了。

public function getUnitPriceFor($entityType,$entityID,$qty,$configuration_id)
{
    $this->qb = $this->getEntityManager()->createQueryBuilder();
    $this->qb   ->select($this->_entities[$entityType]['select'])
                // for Base this would be ->select(array('t','c','w','g'))
                // for the other cases below, like website, it's array('t','w')
                ->from('AcmeBundle:PriceTier', 't');

    switch($entityType) :
        case 'base' :
            $this->qb   ->leftJoin('t.customers','c')
                        ->leftJoin('t.customergroups','g')
                        ->leftJoin('t.websites','w');
        break;
        case 'website' :
            $this->qb   ->join('t.websites','w','WITH','w.id = '.$entityID);
        break;
        case 'custgrp' :
            $this->qb   ->join('t.customergroups','g','WITH','g.id = '.$entityID);
        break;
        case 'cust' :
            $this->qb   ->join('t.customers','t','WITH','t.id = '.$entityID);
        break;
    endswitch;

    $this->qb           ->where('t.printconfiguration = :configuration_id');
    $this->qb           ->setParameter('configuration_id', $configuration_id);

    print_r( $this->qb->getParameters() );

    $dql = $this->qb->getDQL();

    echo"<pre>";
    print_r($this->getEntityManager()->createQuery($dql)->getArrayResult());
    echo"</pre>";
}

打印$this->qb->getParameters();显示我Array ( [configuration_id] => 1 )，删除我的 where 和 set 参数子句可防止发生异常。最后，（并得到这个），如果我删除我的 where 子句但保留参数集，则不会发生异常。我比较困惑。

显然$dql = $this->qb->getDQL();不会传递参数。

我需要改变

$dql = $this->qb->getDQL();

echo"<pre>";
print_r($this->getEntityManager()->createQuery($dql)->getArrayResult());
echo"</pre>";

至

$query = $this->qb->getQuery();

echo"<pre>";
print_r($query->getArrayResult());
echo"</pre>";
