Yii不允许我在SQL查询中使用别名

Question

以下代码返回错误：

       $orders = Yii::$app->db->createCommand("SELECT
                                            Orders.CustomerName AS BillingName
                                              FROM `Orders`
                                              WHERE `CustomerId` = :student_id ORDER BY Orders.`EntryDate` DESC")->bindValues([":student_id" => $student_id])->queryAll();
    $orders_result = [];
    $i = 0;
    foreach ($orders as $order) {
        $total_books_price = 0;
        $orders_result[$i] = [
            "BillingName" => $order["CustomerName"],

        ];

但如果我将SELECT COLUMN AS ALIAS替换为SELECT *，则可以正常使用。
