This article mainly introduces the Symfony query method to everyone, and summarizes and analyzes the specific usage skills of createQuery and getQuery to query data in the form of examples. Friends in need can refer to it. I hope it can help everyone.

1. How to write createQuery

$sql = &#39;SELECT COUNT(DISTINCT(g.goodsId)) FROM AppBundle:GoodsIndex g WHERE g.status = :status&#39;;
$params = array(
 &#39;status&#39; => GoodsIndex::STATUS_NORMAL,
);
if (!empty($keywords)) {
 $params[&#39;keywords&#39;] = "%{$keywords}%";
 $sql .= &#39; AND g.keywords like :keywords &#39;;
}
 if (!empty($warehouseIdList)) {
  $params[&#39;warehouseIdList&#39;] = $warehouseIdList;
  $sql .= " AND g.warehouseId IN :(warehouseIdList)";
 }
$goodsNum = $this->entityManager->createQuery($sql)->setParameters($params)->getSingleScalarResult();

Personal summary:: It means placeholder to prevent SQL injection. So put all the required parameters into the array $params.

2. How to write getQuery

$orderBy = &#39;p.&#39;.$searchOptions[&#39;orderBy&#39;];
$repository = $this->entityManager
 ->getRepository(&#39;AppBundle:GoodsIndex&#39;);
$query = $repository->createQueryBuilder(&#39;p&#39;);
$query->select(&#39;DISTINCT(p.goodsId)&#39;);
$query->where(&#39;p.keywords like :keywords&#39;)
 ->setParameter(&#39;keywords&#39;, "%{$searchOptions[&#39;keywords&#39;]}%")
 ->andwhere(&#39;p.status = :status&#39;)
 ->setParameter(&#39;status&#39;, GoodsIndex::STATUS_NORMAL)
 ->orderBy($orderBy, $searchOptions[&#39;order&#39;])
 ->setFirstResult($pagination[&#39;pageSize&#39;] * ($pagination[&#39;page&#39;] - 1))
 ->setMaxResults($pagination[&#39;pageSize&#39;]);
if (!empty($searchOptions[&#39;warehouseIdList&#39;])) {
 $query->andWhere($query->expr()->in(&#39;p.warehouseId&#39;, $searchOptions[&#39;warehouseIdList&#39;]));
}
$goodsIndexList = $query->getQuery()->getResult();
