🚨 New Video is LIVE — A Concept Most SQL Developers Get Wrong! 🚨

CTE, Temp Table, hSubquery…
Most people know them.
But very few know when to actually use what 👀

In this video, I’ve explained:

✅ Independent vs Correlated Subquery
✅ CTE vs Temp Table
✅ Which one executes first
✅ Which approach is best for interviews & real projects

If you’re preparing for:
• SQL interviews
• Data Analyst / Data Engineer roles
• Real-world SQL work

👉 This video will genuinely clear your confusion.

🎥 Watch now:
👉 Most SQL Developers Get This Wrong 🤯 | CTE vs Temp Table vs Subquery Explained
https://youtu.be/d5Amr7D-5tY

⚠️ Challenge for you:
After watching, tell me in comments —

Which one do you use the most: CTE / Temp Table / Subquery?

Let’s see who really understands SQL 🔥

As promised previously I am back with this

Please watch it and let me know in comments if you liked it

Keep supporting ,keep learning ♥️

📘 Struggling with SQL? Maybe it’s not you… it’s how you’re learning.

Most people jump between random tutorials and get stuck.

But SQL becomes much easier when you follow a structured path:

👉 Basics → Queries → Joins → Indexes → Real-world concepts

This SQL handbook does exactly that — clean, simple, and beginner-friendly.

💡 Stop collecting resources.
Start following one clear roadmap.

Consistency > random learning.

If you’re serious about Data Engineering, start treating SQL like a skill — not just syntax 🚀

In my opinion the best answer here is option 2

Clustering does not always improver performance especially when you are dealing with some small dataset ,at that point ,manual clustering does not make sense

Hey Guys
