Remove by _id in MongoDB console

Removing a Record by _id in MongoDB Console

So, you want to remove a record by _id in the MongoDB console? No worries, I've got your back! It's not as complicated as it seems. Let's dive right into it!

The Problem

In the provided context, the user wanted to remove a record by _id in the MongoDB console. However, the commands they tried didn't work. 🤔

The Solution

To remove a record by _id in MongoDB, you need to use the deleteOne() or deleteMany() method. Here's how you can do it:

db.collectionName.deleteOne({ "_id" : ObjectId("your_id_here") })

or

db.collectionName.deleteMany({ "_id" : ObjectId("your_id_here") })

Let's break down this command:

• db.collectionName refers to the name of the collection where you want to remove the record.

• deleteOne() is used to delete a single record, while deleteMany() is used to delete multiple records.

• { "_id" : ObjectId("your_id_here") } specifies the filter criteria to identify the record you want to remove. Replace "your_id_here" with the actual _id you want to target.

Applying the Solution

In the given scenario, let's assume we have a collection called test_users, and we want to remove the record with _id equal to "4d512b45cc9374271b02ec4f". Here's the correct command to achieve that:

db.test_users.deleteOne({ "_id": ObjectId("4d512b45cc9374271b02ec4f") })

Remember 🧠

Make sure to import the ObjectId class from MongoDB in the console before using the deleteOne() or deleteMany() methods. If you haven't imported it, you might encounter errors.

use your_database_name // Switch to your desired database
ObjectId = require('mongodb').ObjectID // Import the ObjectId class

Conclusion and a Call-to-Action

Removing a record by _id in the MongoDB console is not as intimidating as it might seem at first. Remember to use the proper deleteOne() or deleteMany() method and provide the correct _id value in the filter criteria.
