我是Doctrine的新手。今天我试图从两个sql表中获取一些数据来执行此操作我使用的是doctrine DQL
// $dql = "SELECT c FROM Entities\MainCat c WHERE c.main_cat_id > 0";
$dql = "SELECT c FROM Entities\MainCat c JOIN c.Categories m ORDER BY c.main_cat_id";
$query = $this->doctrine->em->createQuery($dql);
$result = $query->getResult();
foreach ($result as $res) {
echo sprintf("-%s\n", $res->getStatus());
}
第一个注释的DQL语句正在运行，没有任何错误。但是只有join语句会出现一些像这样的错误
Fatal error: Uncaught exception 'Doctrine\ORM\Query\QueryException' with message 'SELECT c FROM Entities\MainCat c JOIN c.Categories m ORDER BY c.main_cat_id' in E:\xampp\htdocs\shoping\application\libraries\Doctrine\ORM\Query\QueryException.php:39 Stack trace: #0
以及更多......
有人可以帮我这个吗？
这是我的Entites / MainCat
