Question

那里，我试图在Symfony2中执行本机MySQL查询，但是我得到一个SQL错误，这是原始查询：

$sql= "SELECT s.id_tariffs_key,s.description,s.voice_rate
  FROM tariffs s
  JOIN (SELECT MAX(id_tariffs_key) AS id FROM tariffs GROUP BY description) max
  ON s.id_tariffs_key = max.id
  WHERE s.description like '$letter%' and s.description not like '%-%'";

这是Symfony2的查询：

$rsm = new ResultSetMapping;
  $rsm->addEntityResult('MyBundle:Tariffs', 't');

  $query = $this->getEntityManager()->createNativeQuery("SELECT t.id_tariffs_key,t.description,t.voice_rate FROM tariffs 
      JOIN (SELECT MAX(t.id_tariffs_key) AS id FROM tariffs GROUP BY t.description) max ON id_tariffs_key = max.id 
       t.description like '?%' and t.description not like '%-%'", $rsm);
  $query->setParameter(1, $letter);

当我尝试加载页面时，它说：

An exception occurred while executing 'SELECT t.id_tariffs_key,t.description,t.voice_rate FROM tariffs 
JOIN (SELECT MAX(t.id_tariffs_key) AS id FROM tariffs GROUP BY description) max ON id_tariffs_key = max.id 
t.description like '?%' and t.description not like '%-%'' with params [23]:

SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 't.description like '?%' and t.description not like '%-%'' at line 3

请帮忙吗？

谢谢！

您将查询翻译成Doctrine时严重损坏了查询，包括忘记WHERE语句。

这是我的Doctrine查询的固定版本

$query = $this->getEntityManager()->createNativeQuery(
    "SELECT t.id_tariffs_key, t.description, t.voice_rate
    FROM tariffs t
    JOIN (
        SELECT MAX(id_tariffs_key) AS id
        FROM tariffs
        GROUP BY description
    ) max ON id_tariffs_key = max.id
    WHERE t.description LIKE ? AND t.description NOT LIKE '%-%'",
    $rsm);
$query->setParameter(1, $letter.'%');
