The dropDatabase() Method

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

Syntax:

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 default 'test' database

Example:

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

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

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

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