MongoDB: Delete Collection

In one of our previous tutorials, we already have created a collection inside a database. In this tutorial, you will be learning how to delete a particular collection.

In MongoDB, a database is composed of collections, and a collection in composed of documents. A collection can only belong to a single database.

To get on with collection, we first need to start the Mongo Daemon and the Mongo Shell.

If you are using a Mac, open your terminal and start the Mongo Daemon first.

				
					$ mongod
				
			

Next, open another new terminal (⌘ + T) and start the Mongo Shell.

				
					$ mongo
				
			

If you are using Windows, go to the /bin directory and double-click on the Mongo Daemon mongod.exe. And in the same /bin directory, double-click on mongo.exe next. This is the Mongo Shell from where you will be entering commands.

We first switch to the books database using the use command. This is where the collection called comics was created.

				
					$ use books
				
			

To delete the comics collection, chain the drop() method to it as shown below:

				
					$ db.comics.drop()
				
			

The comics collection is deleted.
