MongoDB use database_name is used to create a database. The command creates a new database and returns the existing database if it does not exist.

Use database_name

Example:

If you want to create a database name <mydb>, then the USE database statement is as follows:

>use mydbswitched to DB mydb 

To check the currently selected database using command db

>dbmydb

If you want to check the database list, use the command show DBS.

The database created by MyDB does not exist in the list. To display the database, you need to insert it into at least one file.
