MongoDB - Create Database
In this chapter, we will see how to create a database in MongoDB.
The use Command
MongoDB use DATABASE_NAME is used to create database. The command will create a new database if it doesn't exist, otherwise it will return the existing database.
Syntax
Basic syntax of use DATABASE statement is as follows −
use DATABASE_NAME
Example
If you want to use a database with name <mydb>, then use DATABASE statement would be as follows −
>use mydb switched to db mydb
To check your currently selected database, use the command db
>db mydb
If you want to check your databases list, use the command show dbs.
>show dbs local 0.78125GB test 0.23012GB
Your created database (mydb) is not present in list. To display database, you need to insert at least one document into it.
>db.movie.insert({"name":"tutorials point"}) >show dbs local 0.78125GB mydb 0.23012GB test 0.23012GB
In MongoDB default database is test. If you didn't create any database, then collections will be stored in test database.
