学说 2 PlainValue 预期

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:

  1. 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.

  1. 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);
