🚀 SQL SET Operators: The Quick Guide 🚀
Stop trying to solve everything with JOINs! If you need to combine data vertically, these are your best friends:
🔹 UNION Combines results and removes duplicates. Perfect for a clean, unique list. 🧹
🔹 UNION ALL Combines everything, including duplicates. It's much faster because the DB doesn't have to scan for duplicates! ⚡️
🔹 INTERSECT Finds the common ground. Only returns rows that exist in both datasets. 🤝
🔹 EXCEPT / MINUS The "difference" finder. Shows what's in your first query but NOT in the second. 🚫
💡 Pro-Tip for Interviews: Always remember: For SET operators to work, your queries must have the same number of columns and matching data types!

🧠 Amazon SQL Interview Challenge
This is an interesting challenge ,please take a look
Ever tried applying Pythagoras theorem in SQL? 😄
You’re given triangle sides stored row-wise and your task is to identify which CombinationID forms a right-angled triangle.
📐 Rule to apply:
H² = P² + B² (longest side matters!)
If this showed up in an interview, how would you approach it?
