Comment SQL and I’ll send you the link to my book Mastering SQL Window Functions. I used to compare sales using messy self-joins. Slow. Confusing. Hard to explain. Then I learned LAG() and LEAD(). No joins. Cleaner SQL. Better performance. If you’re into SQL or a data analyst looking to optimize queries—this one’s for you. #sql #dataanalyst

Day 36/100 - SQL Challenge: Weather Temperature Comparison 🌤️ In this challenge, we tackle an interesting SQL problem: finding dates with higher temperatures compared to the previous day. The twist? If the previous day doesn’t exist or isn’t consecutive, it’s not considered! Learn how to use window functions like LAG() or self-joins with date differences to solve this efficiently. Perfect for those practicing SQL queries for Amazon, Google, or data analyst interviews. #SQLChallenge #Day36 #100DaysOfSQL #SQLInterview #DataAnalyst #LearnSQL #SQLQuery #GoogleInterview #AmazonInterview #WindowFunctions #SelfJoin #TemperatureComparison #DataEngineering #SQLPractice

There are three main types of window functions used in SQL. 1. Aggregate Window Functions 👉 Perform calculations like SUM, AVG, COUNT, MIN, MAX over a window of rows. Example use: running total, moving average. 2.Ranking Window Functions 👉 Assign a rank or position to rows. Examples: ROW_NUMBER, RANK, DENSE_RANK, NTILE 3.Analytical (Value) Window Functions 👉 Return values from other rows in the window. Examples: LAG, LEAD, FIRST_VALUE, LAST_VALUE Do follow for more such content:@sqlswathimuthyam #mysql #sql #windowfunctions #dataanalyst #sqlswathimuthyam

Day 8/21 – SQL Challenge Solved 4 SQL questions today, mainly using window functions, self joins, and subqueries. • Rising Temperature: Used LAG() to compare today’s temperature with yesterday’s and filtered where today > previous day. (Also possible using self join with date difference logic.) • Customers Who Never Order: Solved using 1.LEFT JOIN + NULL filter 2.NOT EXISTS subquery • Repeated Payments (DataLemur): Used LAG() to get previous transaction timestamp and calculated time difference. Filtered payments repeated within 10 minutes for same card, merchant, and amount. • Employees Earning More Than Their Manager: Solved using self join on employee_id and manager_id and compared salaries. Key learning: Window functions + self joins make comparison-based problems much easier. Day 9 loading…

SQL Window Functions You Should Know If there’s one thing I tell every data professional I mentor: 👉 Master your window functions. They’re what separate basic queries from powerful analytics. Here are my essentials: 🔹 ROW_NUMBER() Rank rows uniquely within a group. 1. RANK() / DENSE_RANK() Handle ties in rankings. Perfect for leaderboards. 2. NTILE(n) Split data into buckets—quartiles, deciles, etc. 3. SUM() OVER() Running totals without losing detail rows. 4. AVG() OVER() See how each row compares to the average. 5. LAG() / LEAD() Access previous or next row values easily. 6. FIRST_VALUE() / LAST_VALUE() Fetch the first or last value in your window. 7. CUME_DIST() Get percentile ranks to spot where each row stands. Why do I emphasize these so much? ✅ They simplify complex reporting. ✅ They keep raw data and summaries together. ✅ They make your queries faster, cleaner, and easier to explain. Don’t let the syntax intimidate you. Start small, practice often. Your future self and your stakeholders will thank you.
