In this post, we will see how to drop a database using the MongoDB command.

The dropDatabase() Method

MongoDB db.dropDatabase() command is used to drop a existing database.

Syntax

The basic syntax of dropDatabase() command is as follows −

db.dropDatabase()

This will delete the selected database. If you have not selected any database, then it will delete the default 'test' database.

First, check the list of available databases by using the command, show dbs.

> show dbs;
admin   0.000GB
config  0.000GB
local   0.000GB

Let's first create a new database with the following command:

> use mydb
switched to db mydb

Now, let's drop this database with dropDatabase() command:

> db.dropDatabase()
{ "dropped" : "mydb", "ok" : 1 }

Now let's use dbs command to show all databases:

> show dbs;
admin   0.000GB
config  0.000GB
local   0.000GB
