问题描述
我在执行 Doctrine DQL 查询时遇到问题.这是它给我的错误.
I'm having trouble executing a Doctrine DQL Query. This is the error it gives me.
DoctrineCommonAnnotationsAnnotationException: [Syntax Error] Expected PlainValue,
got 'integer' at position 13 in property BaseSession::$lifetime.
我的代码如下所示:
$query = $em->createQuery("SELECT s FROM BaseSession s WHERE s.session = "$id"");
其中 $id 是当前 session_id.我的模型看起来像:
Where $id is the current session_id. My Model looks like:
namespace Base;
/** @Entity @Table(name="session") */
class Session extends Skeleton {
/**
* @Id @Column(type="integer")
* @GeneratedValue(strategy="AUTO")
*/
protected $id;
/** @Column(length=32) */
protected $session;
/** @Column(type=integer) */
protected $lifetime;
/** @Column(type=integer) */
protected $modified;
/** @Column(type="text") */
protected $data;
}
推荐答案
你有两个错误:
你必须双引号你的注释，即
@Column(type="integer")而不是@Column(type=integer).当您的映射错误时，会抛出 DoctrineCommonAnnotationsAnnotationException.这与查询无关.
You have to double quote your annotations, i.e.
@Column(type="integer")not@Column(type=integer). DoctrineCommonAnnotationsAnnotationException is thrown when your mapping is wrong. This has nothing to do with the query.
您的查询应该使用准备好的语句，即
Your query should use prepared statements, i.e.
$query = $em->createQuery("SELECT s FROM BaseSession s WHERE s.session = ?1");$query->setParameter(1, $id);
