searchModel中的Yii2列别名

Question

I've got a problem with aliases, trying to get ActiveDataProvider with alias that is min value from 2 tables.

$query->select('karta_przyrzadu.*'); 
        $query->joinWith('dzialania');
        $query->addSelect(['dataVar1' => '(NOW() + interval karta_przyrzadu.co_zostalo day)']);
        $query->addSelect(['dzialania.data_plan as `dataVar2`']);
        $query->addSelect(['least(dataVar1, dataVar2) as nextActionDate']);

Vars in model are declared, and marked as safe in rules():

public $nextActionDate;
public $dateRangeStart;
public $dateRangeEnd;
public $dataVar1;
public $dataVar2;

Filtering

if (!is_null($this->nextActionDate) && strpos($this->nextActionDate, ' - ') !== false ) {
            list($dateRangeStart, $dateRangeEnd) = explode(' - ', $this->nextActionDate);
            $query->andFilterWhere(['between', 'dataVar2', $dateRangeStart, $dateRangeEnd]);
        }

doesn't because of:

SQLSTATE[42S22]: Column not found: 1054 Unknown column 'dataVar1' in 'field list'

The SQL being executed was: SELECT COUNT() FROM (SELECT karta_przyrzadu., (NOW() + interval co_zostalo day) AS dataVar1, dzialania.data_plan as dataVar2, least(dataVar1, dataVar2) as nextActionDate FROM karta_przyrzadu LEFT JOIN dzialania ON karta_przyrzadu.id_przyrz = dzialania.id_przyrz_d WHERE (nextActionDate BETWEEN '2017-02-18' AND '2017-02-24') AND (NOT (status='Wycofany')) GROUP BY id_przyrz) c

Anyone can help me?
