MongoDB Show all contents from all collections

Showing All Collections and Their Contents in MongoDB: The Ultimate Guide

🤔 Have you ever wondered if it's possible to display all collections and their contents in MongoDB? Are you tired of manually displaying collections one by one? Well, you're in luck! In this blog post, we'll explore how to accomplish this task with ease and efficiency. 💪

The Problem: Displaying Collections One by One

⏳ Imagine having a MongoDB database with multiple collections and wanting to view the contents of each collection in one go. The traditional method requires you to individually query each collection, which can be time-consuming and repetitive. 😫

The Solution: MongoDB's db.getCollectionNames() and db.collection.find()

🚀 MongoDB provides two powerful methods that come to our rescue: db.getCollectionNames() and db.collection.find(). Let's take a closer look at how we can use these methods to display all collections and their contents efficiently.

1. Display All Collections: To obtain a list of all collections in your database, you can use the db.getCollectionNames() method. Here's an example:

db.getCollectionNames().forEach(function(collectionName) {
    print(collectionName);
});

This code iterates through all collections and prints their names. 📃

1. Display Contents of All Collections: To display the contents of each collection, we'll combine the db.getCollectionNames() method with the db.collection.find() method. Here's an example:

db.getCollectionNames().forEach(function(collectionName) {
    print("Collection: " + collectionName);
    var collection = db.getCollection(collectionName);
    collection.find().forEach(printjson);
});

In this code snippet, we iterate through each collection, print its name, and then retrieve and print all documents within that collection. 📋
