Yii::$service->info->coll() 这样来查询数据，如何打印出实际生成的sql查询语句

目前，这个得进入coll这个函数，修改代码打印

1.yii2打印query 的sql语法：

$query = User::find()->where(['id'=>[1,2,3,4])->select(['username'])

// 输出SQL语句
$commandQuery = clone $query;
echo $commandQuery->createCommand()->getRawSql();

$users = $query->all();

2.fecmall实例说明，譬如：https://github.com/fecshop/yii2_fecshop/blob/master/services/Customer.php#L625

public function coll($filter = [])
    {
        $query = $this->_customerModel->find();
        $query = Yii::$service->helper->ar->getCollByFilter($query, $filter);
        return [
            'coll' => $query->all(),
            'count'=> $query->limit(null)->offset(null)->count(),
        ];
    }

如果进行打印，可以打断点输出。

public function coll($filter = [])
    {
        $query = $this->_customerModel->find();
        $query = Yii::$service->helper->ar->getCollByFilter($query, $filter);
		// 输出SQL语句
		$commandQuery = clone $query;
		echo $commandQuery->createCommand()->getRawSql();
		exit;
		
        return [
            'coll' => $query->all(),
            'count'=> $query->limit(null)->offset(null)->count(),
        ];
    }

// 输出SQL语句
		$commandQuery = clone $query;
		echo $commandQuery->createCommand()->getRawSql();
		exit;

这样，就报上面的错误

出来报错，自己先看看报错信息！！！

报错："Calling unknown method: yii\\mongodb\\ActiveQuery::createCommand()"

mongodb的query，你打印sql？ mongodb哪有sql？
