php - How to debug MySQL/Doctrine2 Queries?

Question

I am using MySQL with Zend Framework & Doctrine 2. I think even if you don't use Doctrine 2, you will be familiar with errors like

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 'ASC' at line 1

The problem is that I don't see the full query. Without an ORM framework, I could probably echo the sql easily, but with a framework, how can I find out what SQL its trying to execute? I narrowed the error down to

$progress = $task->getProgress();

$progress is declared

// ApplicationModelsTask
/**
 * @OneToMany(targetEntity="TaskProgress", mappedBy="task")
 * @OrderBy({"seq" = "ASC"})
 */
protected $progress;

In MySQL, the task class looks like

CREATE TABLE `tasks` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `owner_id` int(11) DEFAULT NULL,
  `assigned_id` int(11) DEFAULT NULL,
  `list_id` int(11) DEFAULT NULL,
  `name` varchar(60) NOT NULL,
  `seq` int(11) DEFAULT NULL,
  PRIMARY KEY (`id`),
  KEY `tasks_owner_id_idx` (`owner_id`),
  KEY `tasks_assigned_id_idx` (`assigned_id`),
  KEY `tasks_list_id_idx` (`list_id`),
  CONSTRAINT `tasks_ibfk_1` FOREIGN KEY (`owner_id`) REFERENCES `users` (`id`),
  CONSTRAINT `tasks_ibfk_2` FOREIGN KEY (`assigned_id`) REFERENCES `users` (`id`),
  CONSTRAINT `tasks_ibfk_3` FOREIGN KEY (`list_id`) REFERENCES `lists` (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=latin1$$

Most simple solution for debugging queries in Doctrine 2:

$em->getConnection()
  ->getConfiguration()
  ->setSQLLogger(new DoctrineDBALLoggingEchoSQLLogger())
;
