SQLPrep helps data analyst candidates practice SQL in the minutes between real responsibilities.
Work through daily multiple-choice drills, then write real queries against bundled SQLite databases. Every exercise runs locally on your device, so practice is fast, private, and available without an account or internet connection.
What you can practice:
- SELECT, WHERE, ORDER BY, and LIMIT
- Aggregate functions, GROUP BY, and HAVING
- JOIN basics and advanced JOIN patterns
- Subqueries, CASE, and NULL handling
- Window functions
- Mixed interview-style SQL problems
SQLPrep is built for focused interview preparation. It avoids streak pressure, mascots, ads, subscriptions, and account setup. Instead, you get a local practice log, chapter accuracy percentages, structured query diagnostics, and a clean dark interface designed for serious study.
Free practice includes Chapter 1, the first 5 SQLite exercises, and a daily quiz allowance.
Unlock Full Practice Library is a one-time purchase that unlocks the full local bank: 200 interview questions and 60 SQLite exercises. No subscription.
Download SQLPrep and run your first real query in under a minute — no account, no internet required.
