用Doctrine＆Symfony 2.1中的數組查詢查詢

Question

我有一個術語數組，我想在一個Doctrine 2查詢中使用LIKE通配符進行匹配。數據庫是SQL，我正在使用DQL，但查詢生成器解決方案將會很好。 我當前查詢的設置是這樣的：

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的錯誤 「QueryException：語法錯誤] 0行，列62：錯誤：預期文字，得到了 '（'」

是此查詢可能在教義

您會收到這樣的錯誤，因爲查詢期待LIKE語句後的值有沒有這樣類似「像」可能的解決辦法的事，我會考慮：。

// 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();
