MongoDb Cheat Sheet

I am starting to use MongoDB a lot these days, but keep forgetting the commands, so here is a cheat sheet.

Drop Database

use $DATABASE_NAME
db.dropDatabase()

Drop collection

use $DATABASE_THAT_HOLDS_COLLECTION
db.$COLLECTION_NAME.drop()

List everything inside a collection

use $DATABASE_THAT_HOLDS_COLLECTION
db.$COLLECTION_NAME.find()

Create Database Admin User

use [database name here]
db.createUser(
   {
     user: "USERNAME GOES HERE",
     pwd: "PASSWORD GOES HERE",
     roles: [ "readWrite", "dbAdmin" ]
   }
)

This only works on versions 2.6+ and will not work on 2.4.9

Get Version

Outside of the mongo client run:

mongodb --version
