CRUD Operations in SQL

Mastering Data: Let the Power of CRUD Loose!

Hello budding data sorcerers! 👋✨ Are you poised to go on a mystical journey into the database sphere? Ready to emerge as a data manipulation master?

Come let's dive deep into the nucleus of operations often undertaken in databases. Learn to utilize the CRUD toolkit with expertise. So what is CRUD? It is an abbreviation for Create, Read, Update, and Delete.

Think of a treasure chest. You can put in new treasures in it—that's creation. You can also peek at what’s inside—read. You have the power to effect change. Some treasures can be altered—that's update. And if any treasures are dispensable, you can delete them.

Be the Master of Data: Realize the Power of CRUD!

Greetings budding data magicians! Are you ready to venture into the realm of databases? You'll become the master of data manipulation. Get ready to learn about CRUD. This is a unique toolkit for managing data.

What Exactly is CRUD?

CRUD is an acronym. It stands for Create, Read, Update, and Delete. Picture you have a chest. You can put in new treasures—this is Create. You can peek inside—this is Read. Some treasures can be changed—this is Update. You can remove unwanted treasures—this is Delete.

Let's Talk About the Power of CRUD Spells

Create (C)

Creating is akin to adding new treasures to your chest. Picture you found a new gem. Place it in the chest carefully. Let's move to the database world. We can create new entries. Found a new magical creature? Named it "Fire Sprite"? Add it to our "Magical Creatures" list. Look at the example:

CREATE TABLE MagicalCreatures (Name TEXT, Power TEXT);

Read (R)

Reading is like opening your treasure chest and checking what's inside. You might grab a treasure and give it a detailed look.

When it comes to the database realm, we're all about reading. Let's assume that we need to know about each and every magical creature we have on our list. Our ask is straightforward:

SELECT * FROM MagicalCreatures;

Update (U) 🔄

To update is to enhance your treasures. It's a bit like changing a gem's color or shape.

In databases, we can tweak existing information. Perhaps, we wish to change the power of our "Fire Sprite." Here's the SQL code for the update:

UPDATE MagicalCreatures SET Power = 'Flame Taming' WHERE Name = 'Fire Sprite';

Delete (D)

Erasing resembles disposing of a treasure you no longer need. It's a way to make space for fresh and thrilling finds.

In the world of databases, we can eradicate entries. Suppose we find that we have no further use for the "Fire Sprite":

DELETE FROM MagicalCreatures WHERE Name = 'Fire Sprite';
