How do you rename a MongoDB database?

🚀 Renaming a MongoDB Database: The Easy Way! 💪

So, you've discovered a typo in your MongoDB database name and now you're scratching your head, wondering how to fix it. We totally get it! Database management can be a tricky business. But worry not! We've got your back with a simple and effective solution. 🙌

The Problem: Fixing a Typosaurus 🦖

Let's start with the problem at hand. You have a MongoDB database with a name that needs correction. You might have already come across the option to copy and delete the database using the copyDatabase command and dropDatabase command. While this can get the job done, it involves unnecessary steps and can be time-consuming. Plus, deleting your old database holds a certain level of risk if you have valuable data stored within it. 😬

The Solution: Renaming Like a Pro 🎉

Fortunately, MongoDB provides a more elegant solution: the renameCollection command. 🌟 This handy command does exactly what it says on the tin - it renames a collection within a database. But hang on, how does this help if we want to rename the entire database?

The Nifty Workaround: Renaming the Main Collection ✨

MongoDB keeps your database metadata in a collection called system.namespaces. And guess what? The name of your database is stored there too! 🎩 By renaming this collection, we can effectively rename the entire database.

Let's take a closer look at the steps:

1. Step into the database you want to rename:

   use your_current_database_name

2. Now, use the renameCollection command to change the name of the collection to new_database_name:

   db.system.namespaces.renameCollection('new_database_name.system.namespaces')

   🚨 Note: Make sure to replace new_database_name with your desired new name for the database.

3. Finally, switch to the newly renamed database:

   use new_database_name

Voila! You've successfully renamed your MongoDB database without any unnecessary hassle! 🎉
