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.

The dropDatabase Command

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
