本文介绍了原则:FetchAll()有限制的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我想让一个fetchAll()有限制?您是否知道symfony2的实体经理是否有可能?我目前的代码(全部获取,无限制):
$ repository = $ this-> getDoctrine() - > getRepository('MyBundle:Download');
$ product = $ repository-> findAll();
感谢大家。
最好的问候,
编辑:
$ em = $ this-> getDoctrine() - > getRepository('MyBundle:Download');
$ ouput = $ em-> findBy(array(),array('id'=>'DESC'),5);
返回最后5行。
感谢所有。
解决方案
通常有助于检查来源代码
Doctrine\ORM\EntityRepository
public function findAll()
{
return $ this-> findBy(array());
}
public function findBy(array $ criteria,array $ orderBy = null,$ limit = null,$ offset = null)
{
$ persister = $ this-> _em-> getUnitOfWork() - > getEntityPersister($这 - > _entityName);
返回$ persister-> loadAll($ criteria,$ orderBy,$ limit,$ offset);
}
I want to make a fetchAll() with limit ? Do you know if it's possible with the entity manager of symfony2 ?
My current code (Fetch all, without limit):
$repository = $this->getDoctrine()->getRepository('MyBundle:Download');
$product = $repository->findAll();
Thanks you all.Best regards,
EDIT:
$em = $this->getDoctrine()->getRepository('MyBundle:Download');
$ouput = $em->findBy(array(), array('id' => 'DESC'),5);
Return the 5 last rows.
Thanks all.
解决方案
It's often instructive to check the source code.
Doctrine\ORM\EntityRepository
public function findAll()
{
return $this->findBy(array());
}
public function findBy(array $criteria, array $orderBy = null, $limit = null, $offset = null)
{
$persister = $this->_em->getUnitOfWork()->getEntityPersister($this->_entityName);
return $persister->loadAll($criteria, $orderBy, $limit, $offset);
}
