MongoDB: How to update multiple documents with a single command?

📝🔥 Title: MongoDB Magic: Updating Multiple Documents in a Snap!

Hey there techies! 💻 Have you ever been frustrated when trying to update multiple documents in MongoDB? 🤔 Don't worry, I'm here to save the day with a super-efficient solution! Let's dive in and discover how to update multiple documents with just a single command! 🚀

🤨📝 Addressing the Problem:

It seems like our adventurer came across a frustrating problem—a single command only updated one document in their collection! 🐢 But looping through and updating documents one by one... ain't nobody got time for that! 😫

No worries! MongoDB has a clever solution that will spare you the hassle and make your updates a breeze! 💨

🔧💡 The Solution: Update with Multi Option

Using the update() method, we can add the { multi: true } option as the third argument to update multiple documents with a single command. Let me show you how it's done: 🎩

db.test.update({ "foo": "bar" }, { "$set": { "test": "success!" } }, { multi: true });

💡🔍 Explaining the Code:

• The first argument { "foo": "bar" } specifies the criteria for matching documents to be updated. In this case, we update all documents where the field foo has the value of "bar".

• The second argument { "$set": { "test": "success!" } } sets the value of a field called test to "success!" for all matched documents.

• Finally, the third argument { multi: true } is what makes the magic happen! It instructs MongoDB to update multiple documents that match the criteria.

🔥🌟 And Voila! ✨✨

With just a single command, all the documents in the collection that have "foo": "bar" will now have a shiny new "test": "success!" field! 🎉

👏📈 Efficiency Boost: 🚀

By using the { multi: true } option, you save valuable time and resources by avoiding the need for looping and updating each document individually. Your code will run smoothly and efficiently, leaving you with more time for coffee breaks! ☕️
