Symfony2查询不起作用，适用于MySql

Question

我在MySQL中有一个很好的查询，但是在Symfony2中（当使用命名空间设置时）它不起作用。任何人都可以告诉我为什么？

以下是我收到的错误：[语义错误]第0行，第61行附近＆＃39;（＆＃39;：错误：类＆＃39;（＆＃39;未定义。

$query = $em->createQuery("
SELECT  q1.sumQty, q2.totalRows
FROM(
    SELECT      sum(fbaoh.qty) as sumQty
    FROM        WIC\APIBundle\Entity\FBAOrderHistory fbaoh
    WHERE       fbaoh.asin = :asin
    AND         fbaoh.sku = :sku
    AND         fbaoh.webServiceAccountAmazon = :wsaa
    AND         fbaoh.datetimePlaced BETWEEN :startDate AND :endDate)
    q1,
    (
    SELECT      count(fbai.id) as totalRows
    FROM        WIC\APIBundle\Entity\FBAInventory fbai
    LEFT JOIN   WIC\APIBundle\Entity\FBAInventoryReport fbair
    WITH        fbai.fbaInventoryReport = fbair.id
    WHERE       fbai.asin = :asin
    AND         fbai.sku = :sku
    AND         fbai.webServiceAccountAmazon = :wsaa
    AND         fbair.report_datetime BETWEEN :startDate AND :endDate)
    q2
    ");
    $query->setParameters(array(
        'startDate' => $startDate->format('Y-m-d'),
        'endDate' => $endDate->format('Y-m-d'),
        'wsaa' => $webService,
        'sku' => $sku,
        'asin' => $asin,
    ));
    $fbaiDataElements = $query->getArrayResult();

感谢。
