MongoDB - Drop a Database

To drop a collection in MongoDB, use either the db.dropDatabase() method, or the dropDatabase command.

In MongoDB, you can drop a database by switching to that database and running either the db.dropDatabase() method or the dropDatabase command.

The `db.dropDatabase()` Method

Here, we'll use db.dropDatabase() method to drop the current database.

First, let's check our list of databases:

> show databases
local  0.000GB
music  0.000GB
test   0.005GB

Check out list of databases again:

> show databases
local  0.000GB
test   0.005GB

The music database is no longer with us.

You can also use the dropDatabase command to do the same thing.

Resulting message:

{ "dropped" : "test", "ok" : 1 }

And our list of databases has shrunk again:

> show databases
local  0.000GB
