How to form the SQL queries

SQL Magic Spells: Cast Your Database Wonders! 🧙✨

Are you ready to harness the power of SQL and learn the language that brings databases to life? Dive into the enchanting realm of SQL and perform database magic with us. Let's cast some spells!

What is SQL?

SQL, or Structured Query Language, is like a magic wand that allows us to interact with databases. With SQL, we can ask questions of these vast pools of data, gather information, make changes, and organize it neatly. Think of SQL as the tool that brings order to the digital world.

The ABCs of SQL Spells

Let’s explore some essential SQL spells and their uses:

1. SELECT Spellbook 📖

The SELECT spell allows us to fetch information from our magic book (database). It’s like asking a question and receiving an answer:

SELECT * FROM Wizards;

This spell means: "Show me all the wizards!"

2. CREATE Potion 🧪

The CREATE potion is used to make new potions (tables) in our magic lab (database). You choose your ingredients (columns) for the potion:

CREATE TABLE Potions (Name TEXT, Power TEXT);

This potion recipe says: "Create a potion with Name and Power!"

3. UPDATE Transformation 🔄

The UPDATE transformation spell allows you to alter an existing potion's recipe (data). You can pick a potion (table) and adjust its properties (values):

UPDATE Potions SET Power = 'Invisibility' WHERE Name = 'Vanishing Elixir';

This spell states: "Change the power of the Vanishing Elixir potion to Invisibility!"

4. DELETE Vanishing Spell ❌

The DELETE vanishing spell is used to make things disappear (delete data). Choose what you want to vanish from your magic book (database):

DELETE FROM Wizards WHERE Name = 'Dark Sorcerer';

This vanishing spell says: "Make the Dark Sorcerer disappear from the list of wizards!"
