What is the method for querying all data in MongoDB?

In MongoDB, you can use the find() method to query all data. Here is a simple example:

db.collection_name.find()

In this example, collection_name is the name of the collection to be queried. Calling the find() method without passing any conditions will return all documents in that collection.

If you want to sort or limit the returned fields in the query results, you can add other options in the find() method. For example, to query all data and sort them by a specific field, you can do this:

db.collection_name.find().sort({ field_name: 1 })

The query results will be sorted in ascending order by the field_name field. You can also use the limit() method to restrict the number of documents returned.

In MongoDB, the method to retrieve all data is by using the find() method, with the option to add other parameters for additional operations as needed.
