Window functions are one of the most useful SQL skills you can learn! I just uploaded a full breakdown of SQL Window Functions using healthcare data examples, and the goal was simple: make this topic feel clear, practical, and actually useful. Window functions are one of the most valuable SQL skills you can learn because they help you do deeper analysis **without losing row level detail**. That means you can rank records, compare values within groups, build running totals, and analyze trends in a much smarter way. In this video, here’s what to expect: * A simple explanation of what window functions are * A clear breakdown of `OVER()`, `PARTITION BY`, and `ORDER BY` * Easy examples of `ROW_NUMBER()`, `RANK()`, and `DENSE_RANK()` * How to calculate averages and running totals without collapsing your data * How `LAG()` and `LEAD()` help you compare rows * How functions like `NTILE()`, `FIRST_VALUE()`, `LAST_VALUE()`, and `PERCENT_RANK()` work * Real healthcare style examples to make the concepts easier to understand Why are window functions worth learning? * They come up in real analytics work all the time * They make your SQL much stronger and more advanced * They are great for interviews * They help you think like a real analyst, not just someone writing basic queries * Once you understand them, a lot of advanced SQL starts to feel much easier If you're learning SQL and want to get more confident with intermediate concepts, this is definitely a video worth watching. #sql #mysql #sqltutorial #windowfunctions #dataanalytics #learnsql #healthcareanalytics #healthinformatics #healthtech #analytics #dataskills https://lnkd.in/g4NwuTKg
