Syntax error on a doctrine query (Symfony2) - symfony

Question

Im getting a syntax error on this query:
protected function _getimsg($id)
{
$imsgRepository = $this->getDoctrine( )->getRepository( 'DonePunctisBundle:Imsg' );
$imsg = $imsgRepository->findOneBy(array('to' => $id, 'read' => 0 ));
if($imsg) {
$em = $this->getDoctrine()->getEntityManager();
$imsg->setRead('1');
$em->persist( $imsg );
$em->flush( );
return $imsg->getContent();
} else {
return '';
}
}
imsg Entity
<?php
namespace Done\PunctisBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
/**
* Imsg
*
* #ORM\Table(name="imsg")
* #ORM\Entity
*/
class Imsg
{
/**
* #var integer
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**

*
* #ORM\Column(name="to", type="string", length=25)
*/
private $to;
/**

* #ORM\Column(name="content", type="string", length=255)
*/
private $content;
/**
* #var integer
*
* #ORM\Column(name="read", type="integer", length=1)
*/
private $read;
/**
* Get id
*
* #return integer
*/
public function getId()
{
return $this->id;
}
/**
* Set To
*
* #param string $to
* #return Page
*/
public function setTo($to)
{
$this->to = $to;
return $this;
}
/**
* Get to
*
* #return string
*/
public function getTo()
{
return $this->to;
}
/**
* Set content
*
* #param string $content
* #return Page
*/
public function setContent($content)
{
$this->content = $content;
return $this;
}
/**
* Get content
*
* #return string
*/
public function getContent()
{
return $this->content;
}
/**
* Set read
*
* #param integer $read
* #return Imsg
*/
public function setRead($read)
{
$this->read = $read;
return $this;
}
/**
* Get read
*
* #return integer
*/
public function getRead()
{
return $this->read;
}
}
The error output
An exception occurred while executing 'UPDATE imsg SET read = ? WHERE
id = ?' with params {"1":"1","2":1}:
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 'read = '1'
WHERE id = 1' at line 1
Any ideas?

Answer 1

From the MySQL manual: http://dev.mysql.com/doc/refman/5.5/en/reserved-words.html - READ is a reserved word. I'm guessing that's why you're getting the syntax error.
Doctrine can automatically quote the column names for you:
<?php
/** #Column(name="`number`", type="integer") */
private $number;
Add backticks to the colum's name - taken from http://docs.doctrine-project.org/en/latest/reference/basic-mapping.html#quoting-reserved-words

Answer 2

if you use yaml, you can do this
Number:
type: entity
table: `number `
