php – 使用Yii2在sqlserver中选择Schema和table？

我有sql server数据库,它有多个架构.我尝试使用sqlsrv驱动程序从不同模式的表中选择一个,但是表示无效配置,该表不存在.
如何使用sqlsrv驱动程序在表中选择架构？ @H_763_3@myConnection的

<?php 
    return [
        'class' => 'yii\db\Connection','dsn' => 'sqlsrv:Server=192.168.10.70;Database=mydatabase',// MS SQL Server,sqlsrv driver public ip
        'username' => 'user_username','password' => 'user_password','charset' => 'utf8',];
?>

<?php
    namespace app\models;

    use Yii;
    use yii\db\ActiveRecord;

    class transaction extends \yii\db\ActiveRecord
    {
        /**
         * @inheritdoc
         */
        public static function tablename()
        {
            return 'scheR_80_11845@a2.transaction';
        }

        public static function getDb()
        {
            return \Yii::$app->db3;  // use the "db3" application component
        }

        /**
         * @inheritdoc
         */
        public function rules()
        {
            return [[['id','@R_874_10793@er','amount','date','status','description'],'required']];
        }

        /**
         * @inheritdoc
         */
        public function attributeLabels()
        {
            return [
            'id' => Yii::t('app','Uid'),'@R_874_10793@er' => Yii::t('app','@R_874_10793@er'),'date' => Yii::t('app','Date'),'amount' => Yii::t('app','amount'),'description' => Yii::t('app','Item Description'),'status' => Yii::t('app','status'),];
        }
    }
?>

dbo.user1.table1

dbo..table1

return 'scheR_80_11845@a2..transaction';

return 'scheR_80_11845@a2.YOUR_user_NAME_HERE.transaction';
