How to use not equal to inside a Yii2 query

Question

I want to use a yii2 query in which I want to check a not equal to condition. I tried like this but it didn\'t give the desired results. How do I do it?

Answer 1

In case anyone reading this needs to use a REGEXP or similar, this works in Yii2 (2.0.15.1):

->andWhere(['NOT REGEXP', 'column','[A-Za-z]'])
