🚀 Day 5 | SQL Learning (May 5, 2026)
Today I focused on SQL JOINS using Microsoft SQL Server 💻

✔ INNER JOIN → only matching data
✔ LEFT JOIN → all left + matched right
✔ RIGHT JOIN → all right + matched left
✔ FULL JOIN → everything from both tables

🚀 Day 4 — SQL WHERE Conditions
📅 3 May 2026
Learned how SQL actually filters data using logic 🧠

✔ AND = strict
✔ OR = flexible
✔ NOT = reverse
✔ BETWEEN / IN / LIKE = powerful filtering tools

💡 SQL checks data row by row (NOT → AND → OR)
Small operators, big impact
