Day 5, Week 7: PostgreSQL confused me today 😅 Why does an alias work in ORDER BY but fail in HAVING? Because: HAVING runs before SELECT ORDER BY runs after Small win, big clarity ✨ #SQLLearning #PostgreSQL

SQL mistake I see daily 👇 People write complex queries when a simple CASE WHEN solves it. If you can explain logic in words first, writing SQL becomes easy. Think → then code. #SQLTips #DataAnalytics #SQLLearning

Day 32/90 I used OR instead of AND on a government budget dataset. SQL didn’t complain. The worksheet looked fine. The results were wrong. AND narrows truth. OR expands it. SQL doesn’t read intention. Only logic. That mistake changes decisions. #SQLLearning #DataAnalytics
