The name of a MongoDB database.
Returns:A database object.

Used to return another database without modifying the db variable in the shell environment.

You can use db.getSiblingDB() as an alternative to the use <database> helper. This is particularly useful when writing scripts using mongosh where the use helper is not available.

Consider a MongoDB instance with two databases, users and records. The active collection is a part of the users database. The requests collection is a part of the records database.

This operation sets the db object to point to the database named users, and then returns a document count for the active collection.

db = db.getSiblingDB('users')

You can create multiple db objects, that refer to different databases, as in the following sequence of operations:

users = db.getSiblingDB('users')
records = db.getSiblingDB('records')

This operation creates two db objects. Each db object refers to a different database, users or records.

For each database, the query returns:

from a collection in that database.
