image我有以下数据库结构
class voters
{
protected $voterid;
protected $imageid;
protected $action;
}
// $voterid = is the current voter
// $imageid = is the id of the voted image
// $action = is upvote/downvote,delete
如果我想一次查找几个项目,检查列是否存在,会发生什么
就像是
$dummy = findOneBy('voterid'=>1,'imageid'=>2,action=>"upvote");
if($dummy)
{
//column exists!
}
这可能吗？
见
Databases and Doctrine
如果要检索产品,关于某些属性,您只需使用方法findOneBy作为参数作为数组：
$product = $repository->findOneBy(array('name' => 'foo','price' => 19.99));
