Jira issue originally created by user gabrielnn77:

I have a problem when I get database records through a query DQL
and then they are changed by another application
If I repeat the query, Doctrine always return the first value, not the current value of the base


// bootstrap

$cache = new \Doctrine\Common\Cache\ArrayCache();
$config = new Doctrine\ORM\Configuration();
$conn = array(
                'dbname' => $database_name,
                'user' => $cnx_user,
                'password' => $cnx_pass,
                'host' => $cnx_host,
                'driver' => $cnx_type,
                'charset' => 'utf8',
                'driverOptions' => array( 1002 => "SET NAMES 'utf8'" )

            $em = Doctrine\ORM\EntityManager::create($conn, $config);

   $dql = "SELECT s from Register s WHERE = 1";
   $query = $em->createQuery($dql);
// the next line is optional, produces same result
   $res = $query->getResult();
   $orm = reset($res);

   echo " regiter id :".$orm->getId()."  field "$orm->getText()."\n";


I run this code in a terminal, and then edit the registry (field text), but the terminal still shows the same result


Comment created by @beberlei:

Doctrine uses an IdentityMap pattern which leads to this issue.

You need to call "EntityManager#clear()" to clean the in memory cache of Doctrine and fetch records from the database again. or call "EntityManager#refresh($entity)"
