MongoDB Drop Collection

In this article, We are going to see how to drop collection in MongoDB Server. We will see two different ways to drop collection from MongoDB Database. One is from Linux shell and another is from mongo shell.

MongoDB Drop Collection Syntax:

 db.collection.drop()

Examples MongoDB Drop Collection:

1. Create collections

Create empty collection:

db.createCollection("inventory")

Create Collection with data:

  db.records.insert({"SNO":1,"Name":"George","Age":19})
 db.records.insert({"SNO":2,"Name":"Karunakar","Age":18})

2. Verify the collections

 show collections

3. Drop a collection from Linux shell

 mongo test --eval 'db.inventory.drop()'
