在dql-Symfony中使用count

Question

我创建了两个存储库，用于将工资核算周（数据库中已有一周）与工资核算期（用户输入的2周）相匹配。但不断收到错误消息，表示即使匹配也不匹配。工资核算周和工资核算期应完全匹配。

自定义存储库

 public function findBystartdateAndenddate($startdate, $enddate)
    {

       $repository=$this->getEntityManager()->getRepository('comtwclagripayrollBundle:Payrollweek');
       //$startdate='startdate';
       //$enddate='enddate';
       $qb=$repository->createQueryBuilder('pw');
       $qb->select('pw');
       $qb->where('pw.startdate=:startdate');
       $qb->Andwhere('pw.enddate=:enddate');
       $qb->setParameter('startdate', $startdate);
       $qb->setParameter('enddate', $enddate);
       $qb->getquery()->getResult();
    }

   public function countBystartdateAndenddate($startdate, $enddate)
    {
      $qb = $this->createQueryBuilder('pw');
      $qb->select('count(pw.id)');
      $qb->where('pw.startdate=:startdate');
      $qb->Andwhere('pw.enddate=:enddate');
      $qb->setParameter('startdate', $startdate);
      $qb->setParameter('enddate', $enddate);

    return $qb->getQuery()->getResult();
    }

控制器

 public function createAction(Request $request)
    {



        $entity = new Payrollperiod();

        $form = $this->createCreateForm($entity);

        $form->handleRequest($request);


            if ($form->isSubmitted() && $form->isValid()) { 

            $em = $this->getDoctrine()->getManager();

            $payrollperiod = $em->getRepository('comtwclagripayrollBundle:Payrollperiod')->findOneBy(['startdate'=>$form->get('startDate')->getData(), 'enddate'=>$form->get('endDate')->getData()]);

            $payrollweek = $em->getRepository('comtwclagripayrollBundle:Payrollweek')->findBystartdateAndenddate($entity->getStartDate() , $entity->getEndDate());

            $counter = $em->getRepository('comtwclagripayrollBundle:Payrollweek')->countBystartdateAndenddate($entity->getStartDate() , $entity->getEndDate());


           if($counter){
            //If entity exists
            if ($payrollperiod){
                    $this->addFlash('error', 'Error: A payroll period is already present with the same start and end date.');
                    return $this->redirect($this->generateUrl('payrollperiod'));
                }
                //If PayrollWeek matches the Payrollperiod entered
               elseif ( $payrollweek){
                foreach ($payrollweek as $pWeek) {
                    $pWeek->setPayrollperiodid($entity); 
                    $em->persist($pWeek);
                }

              $em->persist($entity);
              $em->flush();

                $this->addFlash('success', 'Payroll Period was added.');
                $this->addFlash('success', 'Payroll week was updated.');
                return $this->redirect($this->generateUrl('payrollperiod'));
               //return $this->redirect($this->generateUrl('payrollperiod_show', array('payrollperiodid' => $entity->getpayrollperiodid())));
                 }
                 else{
                   $this->addFlash('error', 'Payroll Period does not match a payroll week.');
                return $this->redirect($this->generateUrl('payrollperiod'));  
                 }
           }

           //return $this->render('comtwclagripayrollBundle::new.html.twig',array('form' => $form->createView()));
           return array(
               'entity' => $entity,
               'form'   => $form->createView(),
           );   

            }
    }
