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
