The use Command

MongoDB use DATABASE_NAME is used to create a database. The command will create a new database if it doesn’t exist, otherwise, it will return the existing database.

Syntax

The basic syntax of use DATABASE statement is as follows −

use DATABASE_NAME

Example

If you want to use a database with the name , 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 the list. To display the database, you need to insert at least one document into it.

>db.movie.insert({“name”:”codelivly”}) >show dbs  local 0.78125GB  mydb 0.23012GB  test 0.23012GB

In MongoDB default database is tested. If you didn’t create any database, then collections will be stored in the test database.
