Doctrine2 SQLSTATE [42000]:语法错误或访问冲突:1064

user.php的;

LikePage.php;



LikeArticle.php;



namespace Acme\DemoBundle\Entity;

use Doctrine\ORM\Mapping as ORM;

/**
 * @ORM\Entity
 * @ORM\Table(name="like_article")
 */
class LikePage extends Like
{
    /**
     * @ORM\Column(type="integer")
     */
    protected $itemid;

   /**
     * @ORM\ManyToOne(targetEntity="Article", inversedBy="likes")
     * @ORM\JoinColumn(name="itemid", referencedColumnName="id")
     */
    protected $article;


我以这种方式向数据库添加数据.我正在尝试从Page Entity中检索数据.但是,执行此时;

$likes = $page->getLikes();
foreach($likes as $like) {

}


我收到这个错误; 

An exception occurred while executing 'SELECT t0.id AS id1, t0.userid AS userid2, t0.itemid AS itemid3, t0.userid AS userid4, t0.itemid AS itemid5, t0.itemtype FROM like t0 WHERE t0.itemid = ? AND t0.itemtype IN ('1')' with params [1]:

SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'like t0 WHERE t0.itemid = '1' AND t0.itemtype IN ('1')' at line 1


在这种情况下,我该怎么办？为什么找不到itemid？
