If you understand SQL Execution Order, you'll understand WHY SQL behaves the way it does in interviews and real projects.

━━━━━━━━━━━━━━━━━━━━━━

🧠 Actual SQL Execution Order

1️⃣ FROM 2️⃣ WHERE 3️⃣ GROUP BY 4️⃣ HAVING 5️⃣ SELECT 6️⃣ DISTINCT 7️⃣ ORDER BY 8️⃣ LIMIT

━━━━━━━━━━━━━━━━━━━━━━

📝 We WRITE SQL Like This

SELECT FROM WHERE GROUP BY HAVING ORDER BY LIMIT

━━━━━━━━━━━━━━━━━━━━━━

⚡ But SQL EXECUTES Like This

FROM ↓ WHERE ↓ GROUP BY ↓ HAVING ↓ SELECT ↓ DISTINCT ↓ ORDER BY ↓ LIMIT

━━━━━━━━━━━━━━━━━━━━━━

🤯 Interview Question

Why can't you use a SELECT alias inside WHERE?

✅ Because WHERE executes BEFORE SELECT.
