What are some basic commands in MongoDB?

MongoDB never creates empty databases. To create there should be at least one collection. There is a single command to switch or create a MongoDB Database.

use DATABASE_NAME

We need to get current database name to verify if it switched correctly or not. To check current database name there is an object of database:

db;

for example: 

>db

myTestDB

>

To list all databases use:

show dbs;

To delete/drop databases use:

db.dropDatabase()

Following is the syntax of USE command .db.dropDatabase()
