In this chapter, 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.
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 a new database <mydb>, then dropDatabase() command would be as follows −
>use mydb
switched to db mydb
>db.dropDatabase()
>{ "dropped" : "mydb", "ok" : 1 }
>
Now checklist of databases.
>show dbs
local 0.78125GB
