use DATABASE The basic syntax of the statement is as follows-

use DATABASE_NAME

Online Examples

If you want to use a database with name<mydb>thenuse DATABASEThe statement is as follows:

>use mydb

To check the database you are currently using, use the following command db

>db
mydb

To check the list of databases, use the following command show dbs.

>show dbs
local　　　　　0.78125GB
test　　　　　　0.23012GB

The database (mydb) you created is not on the list. To display the database, you need to insert at least one document.

>db.movie.insert({"name":"oldtoolbag.com")
>show dbs
local　　　　　　0.78125GB
mydb　　　　　　　0.23012GB
test　　　　　　　0.23012GB

By default, the default database in MongoDB is test. If you have not created any database, the collection will be stored in the test database.
