Question

我使用运行某些查询的方法创建服务，我想使用doctrine Native SQL，但无论我使用哪个查询，它总是返回一个空数组。有些东西我不见了？

来自服务MonthVacancySchedule的方法：

public function getTotalVacanciesByUnits()
{

  $rsm = new ResultSetMapping();

  $sql = 'SELECT nome_procedimento FROM programacao';
  $query = $this->emi->createNativeQuery($sql, $rsm);
  $units = $query->getResult();

  return $units;
}

我使用该服务的控制器：

/**
  * @Route("/units", name="units")
  */
  public function showTotalVacanciesByUnits( MonthVacancySchedule $mvs )
  {

    $units = $mvs->getTotalVacanciesByUnits();

    # Always return empty array.
    var_dump($units);

    return $units;
  }

那是因为你问Doctrine是否为空数组。在public function getTotalVacanciesByUnits() { $rsm = new ResultSetMapping(); $rsm->addScalarResult('nome_procedimento', 'nome_procedimento'); $sql = 'SELECT nome_procedimento FROM programacao'; $query = $this->emi->createNativeQuery($sql, $rsm); $units = $query->getResult(); return $units; }对象中描述您需要的字段。例如

.text-that-needs-wrapping {
    overflow-wrap: break-word;
    word-wrap: break-word;
    -ms-word-break: break-all;
    word-break: break-word;
    -ms-hyphens: auto;
    -moz-hyphens: auto;
    -webkit-hyphens: auto;
    hyphens: auto;
}

使用Native SQL的Doctrine查询始终返回空数组
