Каков правильный синтаксис для передачи статической строки с помощью запроса select?

Question

Это мой запрос в контроллере Yii. Я пытаюсь передать имя контроллера как статическую строку. Этот синтаксис выдает ошибку

«Неправильный синтаксис возле ключевого слова LEFT».

Если я использую:

'Message' AS controllerName, 

... то он работает отлично.

Полнофункциональный:

/** 
* Datatable: Message 
* 
* @param $status 
*/ 
public function actionMessage($status) { 
    // only allow ajax requests to this action 
    if (!Yii::app()->request->isAjaxRequest && !YII_DEBUG) { 
     Yii::app()->end(); 
    } 

    // start building the create command 
    $command = Yii::app()->db->createCommand() 
     ->select(" 
      {Yii::app()->controller->id} AS controllerName, 
      Message.MessageID AS primaryKey, 
      Message.Name AS messageName, 
      Message.Code AS messageCode, 
      Message.CloneOf AS messageCloneOf,

Вы должны использовать параметр связывания для этого:

$command = Yii::app()->db->createCommand() 
    ->select(" 
     :controllerid AS controllerName, 

...

->order('Message.Name ASC') 
->bindParam(':controllerid', Yii::$app->controller->id);
