Deletemany Function In Mongodb

In this article, we will discuss the deleteMany function in MongoDB.

Purpose

The deleteMany function deletes one or more than one document based on the filter criteria.

Consider the following documents: -

We are required to delete the subject name where the subject name is not equal to CSS.

So, the query would be: -

db.Articles.deleteMany({subject:{$ne:”CSS”}})

To delete all documents from the collections, we can use the following command: -

db.[collection_name].deleteMany({})
