Yii2使用mongodb查找查询

Question

我想使用类似的查询：

Select * from company where id is not null order by id desc

我正在使用YII2框架和mongodb：

$company = Company::find()->where(['id' => null])->all();

以上查询对我来说很好，但我想使用NOT NULL条件和order by。我怎么能这样做？

Answer 1

尝试 $company = Company::find()->where(['not', ['id' => null]])->orderBy('id desc')->all();

Answer 2

$company = (new Query)->from('company')->where(['NOT IN','_id',NULL])->all();
