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.

Order : FROM → JOIN → WHERE → GROUP BY → HAVING → SELECT → ORDER BY → LIMIT Explanation: 1. FROM ✅ • SQL first decides which tables it will use. • It loads the data from those tables. 2. JOIN✅ • If your query has joins, SQL will next connect the tables based on join conditions. 3. WHERE✅ • Filters rows. • Removes rows that do not meet your conditions.​ 4. GROUP BY✅ • Groups remaining rows into small buckets based on columns. • Required when you use aggregate functions: COUNT(), SUM(), AVG() etc. 5. HAVING✅ • Works like WHERE, but after grouping. • Filters groups instead of individual rows. ​ 6. SELECT✅ • Now SQL picks which columns or calculations to show. • This is where alias names are applied. 7. ORDER BY✅ • Sorts the final result (ascending / descending). 8. LIMIT / TOP✅ • Finally, SQL returns only the requested number of rows.

COMMENT SQL and I will send you the book link in the DM 📘 Most people think handling NULLs in SQL is simple… until window functions enter the picture. Using COALESCE feels correct, but it doesn’t fix the actual calculation. That’s where most queries go wrong. IGNORE NULLS is a small tweak, but it completely changes your result. Learn these small details, and your SQL becomes business-ready.

If I had to learn SQL again in 2026, this is the roadmap I’d follow. Most people don’t fail at SQL because it’s hard. They fail because they learn it in the wrong order. 1.
