    For combine the result of two or more select query we use union in sql query.If you want to use union in yii query you can use the below code

    $queryFirst = (new \yii\db\Query())
    ->select("id, name")
    ->from('tableA')
    ->limit(10);

$querySecond = (new \yii\db\Query())
    ->select('id, name')
    ->from('tableB')
    ->limit(10);

$queryFirst->union($querySecond);

    this will be equivalent to 

    SELECT id,name FROM tableA
UNION
SELECT id,name FROM tableB;
    union in yii union in yii query
