Php 通过select查询传递静态字符串的正确语法是什么？

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。此语法引发错误

“左关键字附近的语法不正确。”

如果我使用：

'Message' AS controllerName,

…那么它工作得很好

全部功能：

/**
 * 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()
        ->select("
            {Yii::app()->controller->id} AS controllerName,
            Message.MessageID AS primaryKey,
            Message.Name AS messageName,
            Message.Code AS messageCode,
            Message.CloneOf AS messageCloneOf,
            Message.IsActive AS messageIsActive,
            Message.IsArchived,
            Client.Name AS clientName,
            Workflow.WorkflowID AS workflowID,
            Workflow.Name AS workflowName,
            Workflow.Color AS workflowColor,

您必须为此使用参数绑定：

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

请将抛出的错误添加到问题中。请在问题中添加您正在使用的SQL变体。请在您的示例问题代码中添加足够的内容，以使开始括号“（“与结束括号配对”）”。根据代码片段，我无法判断您的代码看起来是否像

..->select（“…from table”）

或者像

..->select（“…”）from table

。请尝试var\u dump查询var\u dump（$command->sql）生成的行sql因此，请看一看有效执行的sql命令。它没有完成命令，所以我应该将var_dump语句放在哪里？这个特殊的功能已经平稳运行了相当长的一段时间。我只添加了一行来打断它。该命令在调用$command->queryAll（）时执行。。。但由createCommand生成，不执行。。因此，您应该使用命令..var_dump（$command->sql）获取sql代码啊哈！谢谢你的信息。

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