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…

Ep58 - 75 SQL Problems!! Most people don’t fail data analyst interviews because they don’t know SQL They fail because they don’t practice the right type of questions. I’ve seen many candidates spend weeks learning SQL concepts — but when real interview questions are asked, they struggle with how to apply the logic. That’s why this list of compiled 75 real world SQL problems will help you to prepare for any data related roles. These questions will help you understand: • how interview questions are framed • how to approach joins, aggregations, case statements logically • how to improve problem solving speed • how to gain confidence before interviews Follow @fitwit_krish and comment SQL. I’ll send the complete list. Save this reel so you can start practicing before your next interview.
