Jira issue originally created by user mjh_ca:

Is this possible? Examples:

$myEntity->createdAt = new \Doctrine\ORM\Expression('CURRENT_TIMESTAMP');
$em->persist($myEntity);

/*** @Entity @HasLifeCycleCallbacks **/
class MyEntity {
    /****
     * @Column(type="string", columnDefinition="BINARY(16) NOT NULL")
     */
   public $md5;

   /****
    * @PrePersist
    */
   public function doSomethingOnPrePersist()
   {
       if (isset($this->md5)) $this->md5 = new \Doctrine\ORM\Expression('UNHEX(\'' . $this->md5 . '\'));
   }
}

$myEntity->md5 = md5('some string');
$em->persist($myEntity);
