💡 Did You Know?
In 1947, computer scientist Grace Hopper helped uncover the world’s first actual computer bug — a literal moth stuck in a computer relay. 🐛💻

That moment sparked the term we still use today when fixing software: "debugging."

Grace wasn’t just solving problems — she was pioneering the future of computing. A true trailblazer in tech. 🚀

Whether you're just learning SQL or brushing up your skills, understanding the basics is key. Today, we’re breaking down 3 essential SQL terms:

🧠 SELECT Statement – An SQL command used to retrieve data from one or more tables in a database.
