MongoDB - Drop Database

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

The dropDatabase() Method​

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

Syntax​

The basic syntax of the 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.

Example​

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

> show dbs
local      0.78125GB
mydb       0.23012GB
test       0.23012GB

If you want to delete the new database mydb, the dropDatabase() command would be as follows:

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

Now check the list of databases:

> show dbs
local      0.78125GB
test       0.23012GB
