💡 Finally Understood Recursive CTEs in SQL! Here's a Step-by-Step Example to Generate Number Sequences (1 to 5) 🔁

Hey everyone! 👋

I recently wrapped my head around Recursive CTEs in SQL, and I created a detailed, beginner-friendly video that explains the concept using a super simple use case — generating a number sequence from 1 to 5, all through SQL!

🔍 In the video, I cover:

What is a Recursive CTE?
How the anchor and recursive member work
Step-by-step breakdown of how SQL executes the recursion
Real-world uses (like traversing hierarchies or building sequences)
Common pitfalls (infinite recursion, missing termination conditions)

🎥 Watch the tutorial here →
Part 1 : https://youtu.be/Qx29pPgQAVM
Part 2 : https://youtu.be/sb-rcjhhfhE

🧠 Great for: SQL beginners, interview prep, and anyone curious about recursion inside databases.

Would love to get feedback, especially if you're learning or teaching SQL.

Let’s make recursive CTEs less scary for beginners! 💪
