$conn = $this->getDoctrine()->getConnection();
$hasAnswer = $conn->fetchAssoc("SELECT * FROM p_question_answer where testPaperResultId = ? and questionId = ? and type = ?", [$id, $questionId, $type]);
if($hasAnswer) {
$res = $conn->executeQuery("update p_question_answer set con = ? where id = ?", [$con, $hasAnswer['id']]);

}
生成doctrine 映射关系文件: https://symfony.com/doc/2.3/book/doctrine.html
预定义文中用到的变量：
$em = $this->getDoctrine()->getEntityManager();$repository = $em->getRepository(‘AcmeStoreBundle:Product’)；
1.常用的查询
$repository->find($id); //获取的是一条数据
$repository->findAll(); //获取的是数组
$repository->findOneByName(‘Foo’);//获取的是一条数据
$repository->findBy(array(‘name’ => ‘foo’，‘price’ => 19.99),array(‘price’ => ‘ASC’));//获取的是一个数组
2、DQL
例题1.
$query = $em->createQuery(
‘SELECT p FROM AcmeStoreBundle:Product p WHERE p.price > :price ORDER BY p.price ASC’
)->setParameter(‘price’, ’19.99′);$products = $query->getResult();注：
（1） 获得一个结果可以用：$product = $query->getSingleResult();（2） setParameter(‘price’, ’19.99′);运用这个外部方法来设置查询语句中的 “占位符”price 的值，而不是直接将数值写入查询语句中，有利于防止SQL注入攻击，你也可以设置多个参数：->setParameters(array(
‘price’ => ’19.99′,
‘name’ => ‘Foo’,
))
3.Query Builder查询
分页的查询
$repository = $this->getDoctrine()
->getRepository('AppBundle:Goods');
$query = $repository->createQueryBuilder('p')
->where('p.name like :name')
->andwhere('p.status = 0')
->setParameter('name', "$fuzzyGoodsInfo")
->orderBy('p.sales', 'DESC')
->setFirstResult($pageSize * $page)
->setMaxResults($pageSize) //相当于limit 取多少条数据 setLimit(100);
->getQuery();
$goodsList = $query->getResult();
例:queryBuilder方法：查询一个数组结果
materialId等于$materialId，并且action在$actionList数组内的。并且按照时间排序
$queryBuilder = $this->getEntityManager()->createQueryBuilder();
$resultList = $queryBuilder->select('s')
->from('AppBundle:StockHistory', 's')
->Where('s.materialId = :materialId')
->andWhere($queryBuilder->expr()->in('s.action', $actionList))
->orderBy('s.createTime', 'DESC')
->setParameter('materialId', $materialId)
->getQuery()->getResult();
4.SQL的更新
$query = $em->createQuery("UPDATE AppBundle:ReceiverAddress u SET u.defaultFlag = 0 WHERE u.userId = :userId")->setParameter('userId',$userId);
$result = $query->getResult();
更新一个对象包括三步：
1.从Doctrine取出对象
2.修改对象
3.在实体管理者上调用flush()方法
$em = $this->getDoctrine()->getEntityManager();
$repository = $em
->getRepository(‘AcmeStoreBundle:Product’)
->find($id);；
if (!$repository) {
throw $this->createNotFoundException('No product found for id '.$id);
}
$repository->setName('New product name!');
$em->flush();
return $this->redirect($this->generateUrl('homepage'));
5.删除
删除一个对象，需要从实体管理者那里调用remove()方法。
$em->remove($repository);
$em->flush();
remove()方法告诉Doctrine你想从数据库中移除指定的实体。真正的删除查询没有被真正的执行，直到flush()方法被调用。
6.增加数据
$product = new Product();$product->setName('A Foo Bar');
$product->setPrice('19.99');
$product->setDescription('Lorem ipsum dolor'); $em = $this->getDoctrine()->getManager();$em->persist($product);$em->flush();$product->getId();
批量写入例子:
/**
* 批量写入数据
*
*@author wyl
*@param string $entity
*@param array $dataList
*@param array $per
*/function batchInsertByEntity($entity, $dataList, $per = 1000)
{
$count = count($dataList);
for ($i = 0; $i < $count; $i ++) {
$obj = new $entity();
foreach ($dataList[$i] as $k => $v) {
$obj->{"set" . $this->ucWords($k)}($v);
}
$this->em->persist($obj);
if (($count % $per) === 0) {
$this->em->flush();
$this->em->clear();
}
} // 除不尽剩下的还是要保存的
$this->em->flush();
$this->em->clear();
}
二、mongodb的操作
更新操作
->multiple(true)这句话的意思，可以删除所有goodsId==$goodsId的记录，不加的话，就只删除第一条数据
// 更新当前goodsId下的所有Material 状态status
$dm = $this->get('doctrine_mongodb')->getManager();
$dm->createQueryBuilder('AppBundle:Material')
->update()
->multiple(true)
->field('status')->set(2)
->field('goodsId')->equals($goodsId)
->getQuery()
->execute();$dm->flush();
1.根据id直接查询一条记录
$dm = $this->get('doctrine_mongodb')->getManager();
$material = $dm->getRepository('AppBundle:Material')->find(new \MongoId($materialId));
2.往mongodb表中插入一条数据
$product = new Product();
$product->setName('A Foo Bar');
$product->setPrice('19.99');$dm = $this->get('doctrine_mongodb')->getManager();
$dm->persist($product);
$dm->flush();
//定义量 $repository = $this->get('doctrine_mongodb') ->getManager() ->getRepository('AcmeStoreBundle:Product');
1.根据$id查询数据
$product = $repository->find($id);$product = $repository->findOneById($id);$product = $repository->findOneByName(‘foo’);// find *all* products$products = $repository->findAll();$products = $repository->findByPrice(19.99);
$product = $repository->findOneBy(array(‘name’ => ‘foo’, ‘price’ => 19.99));
//多个条件查询
$products = $repository->findBy(
array(
'name' => 'foo',
'status' => 0,
),
array('price', 'ASC')
);
//查询一条语句后，更改某个字段的值
$dm = $this->get('doctrine_mongodb')->getManager();
$product = $dm->getRepository('AcmeStoreBundle:Product')->find($id);
if (!$product) {
throw $this->createNotFoundException('No product found for id '.$id);
}$product->setName('New product name!');
$dm->flush();
二、Query Builder查询
$products = $this->get('doctrine_mongodb')
->getManager()
->createQueryBuilder('AcmeStoreBundle:Product')
->field('name')->equals('foo')
->limit(10)
->sort('price', 'ASC')
->getQuery()
->execute()
