这是我在Yii控制器中的查询。我试图将控制器的名称作为静态字符串传递。此语法将引发错误
“关键字LEFT附近的语法不正确。”
如果我使用：
'Message' AS controllerName,
...然后它运作正常。
完整功能：
/**
* 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()

您必须使用参数绑定：
$command = Yii::app()->db->createCommand()
->select("
:controllerid AS controllerName,
...
->order('Message.Name ASC')
->bindParam(':controllerid', Yii::$app->controller->id);
