Yii2 - query in controller -> where?

Question

Yii

Hi everyone I
have a request:

$query = Product::find()->where(['status' => '1', 'price2' => ' *** '])->addOrderBy('id DESC');

What should I write instead of *** so that if there is at least some information in the database, the condition would be fulfilled
I can’t find it in the documentation

Answer 1

->andWhere(['not', ['price2' => null]])
или
->andWhere(['is not', 'price2', null])

Answer 2

Maybe ['like', 'title', $this->title] ?
