Phalcon 2.1.0 executeQuery（） - 子查询

Question

$phql = "SELECT t1.* FROM (SELECT u.* FROM \App\Models\User as u) as t1";
$modelsManager = new \Phalcon\Mvc\Model\Manager();
$modelsManager->setDI($this->getDi());
$query = $modelsManager->executeQuery($phql);

  

语法错误，意外令牌（靠近'SELECT u。* FROM   \ app \ Models \ User as u）as t1'，解析时：SELECT t1。* FROM   （SELECT u。* FROM \ App \ Models \ User as u）as t1（62）

有什么问题？
