如何在Yii ActiveRecord中创建IS NOT NULL where子句？

Question

我尝试了以下

$kw = Keyword::find()->leftJoin('ad_group_keyword', 'keyword_id = keyword.id')->where(['keyword_id' => null, ['not', ['revenue' => null]]])->all();

但它给了我一个错误

  

PHP警告 - yii \ base \ ErrorException   strtoupper（）期望参数1为字符串，给定数组为

使用andWhere：

进行更改

$kw = Keyword::find()
             ->leftJoin('ad_group_keyword', 'keyword_id = keyword.id')
             ->where(['keyword_id' => null])
             ->andWhere(['not', ['revenue' => null]])
             ->all();
