🚀 Master the Most Powerful SQL Keywords: EXISTS, IN, ANY, ALL – Explained with a Store Management System Project!

In this hands-on SQL tutorial, we explore four essential SQL conditional keywords—EXISTS, IN, ANY, and ALL—within the context of a real-world Store Management System. Understand how these keywords work behind the scenes and how to use them to write smarter, more dynamic queries.

💡 What You’ll Learn:

How to use EXISTS to check for related records

The difference between IN vs EXISTS

When to use ANY and ALL with comparison operators

Real examples using customers, orders, order_details, and products
