📝 CRUD Operations in SQL Explained | Create, Read, Update, Delete Made Simple
Databases are like notebooks — you can write new notes, read them, update them, or erase them. That’s CRUD in action! 🚀
In this beginner-friendly tutorial from Medha XL, you’ll learn the four core operations that power every database system:
👉 C → Create (INSERT)
INSERT INTO employees (name, salary) VALUES ('Alice', 60000);
✔️ Adds a new row to the table
👉 R → Read (SELECT)
SELECT * FROM employees;
✔️ Displays all stored data
👉 U → Update (UPDATE)
UPDATE employees SET salary = 65000 WHERE name = 'Alice';
✔️ Edits existing records
👉 D → Delete (DELETE)
DELETE FROM employees WHERE id = 3;
✔️ Removes unwanted rows
📊 We’ll use animations and real-life analogies to make CRUD crystal clear — like editing your phone contacts, deleting notes, or adding new records.
✨ Why CRUD Matters:
Powers every app you use daily
E-commerce → add products, update prices, delete old listings
Banking → create accounts, update balances, close accounts
Social media → post (create), view (read), edit (update), delete (remove)
By the end of this video, you’ll understand the foundation of SQL and database management.
