yii2 SUM用法

(new \yii\db\Query())
                        ->select(["SUM(ht_sina.sina_fans) as fans","SUM(ht_sina) as ones"])
                        ->from('ht_sina')

                        ->innerjoin("ht_admin","ht_adn.admin_id=ht_sina.n_id")
                        ->where($where)
                        ->andwhere($weiboname)
                        ->andwhere($weiboid)
                        ->andwhere($sinafans) 

			->andwhere($updatetime)
                        ->all();



多条件查询   放进数组

        $weiboname = "";
        if(!empty($sinaame))
        {
            $weiboname = ['like','ht_sina.na_name',$sa_name];
        }
        $weiboid = "";
        if(!empty($sina_nmber))
        
            $weiboid = ['like','ht_sina.sina_umber',$sina_nur];
        }
        $sinafans = "";
        if(!empty($sina_fans) && !empty($sina_f-09anss))
        {
            $sinafans = ['between', 'ht_sina.na_fans', "$si_fans", "$iu"];
        }else
        {
            if(!empty($na_fans))
