This was such an insightful read! The breakdown of IS NULL vs. = NULL really cleared up some common misconceptions, and the distinction between COUNT(*) and COUNT(column_name) was a great refresher. Also, the reminder about using the right order with UNION ALL is something every SQL user needs to keep in mind. Thanks for sharing these sneaky traps, we definitely need to watch out for them!
