用Doctrine＆Symfony 2.1中的数组查询查询

Question

我有一个术语数组，我想在一个Doctrine 2查询中使用LIKE通配符进行匹配。数据库是SQL，我正在使用DQL，但查询生成器解决方案将会很好。 我当前查询的设置是这样的：

foreach($textterms as $text) 
{ 
$parameters[] = '%-'.$text.'-%'; 
} 

$em = $this->getDoctrine()->getManager(); 
$query = $em->createQuery(
'SELECT p FROM Post p WHERE p.searchfield IN LIKE (:text) ORDER BY p.datetime DESC' 
     )->setParameter('text', $parameters); 
     $posts = $query->getResult(); 

，但我得到symfony的错误 “QueryException：语法错误] 0行，列62：错误：预期文字，得到了 '（'”

是此查询可能在教义

您会收到这样的错误，因为查询期待LIKE语句后的值有没有这样类似“像”可能的解决办法的事，我会考虑：。

// Query Builder added to show difference in code readability I personally use queryBuilder mostly 
$query = $this->getDoctrine()->getManager()->createQueryBuilder(); 
$query->select('p') 
     ->from('Post', 'p') 
     ->orderBy('p.datetime', 'DESC'); 
$i = 0; 
$parameters = array(); 
foreach ($textterms as $key => $text) 
{ 
    $query->orWhere('p.searchfield LIKE ?' . $i++); 
    $parameters[] = '%-' . $text . '-%'; 
} 
$query->setParameters($parameters); 
$posts = $query->getQuery()->getResult(); 

// Query 
$orX = new \Doctrine\ORM\Query\Expr\Orx(); 
$i = 0; 
$parameters = array(); 
foreach ($textterms as $text) 
{ 
    $orX->add('p.searchfield LIKE ?' . $i++); 
    $parameters[] = '%-' . $text . '-%'; 
} 
$orX = (string)$orX; 
if(!empty($orX)) 
{ 
    $orX = 'WHERE ' . $orX; 
} 
$sql = sprintf('SELECT p FROM Post p %s ORDER BY p.datetime DESC', $orX); 
$query = $this->getDoctrine()->getManager()->createQuery($sql); 
$query->setParameters($parameters); 
$posts = $query->getResult();
