Description
On Android, iPhone and the web, with your progress synced across all of them.
Every day there’s a new SQL interview question too, adapted from real questions asked at top tech companies, in collaboration with StrataScratch. It’s free, and it counts toward your streak.
TWO COURSES
- SQL Fundamentals (beginner): nine modules, from your first SELECT to window functions
- Real-World SQL (intermediate, new): six modules on the messy data you meet at work, like duplicates, missing values, messy text, and joins that count things twice
WHAT YOU’LL LEARN
- SELECT, FROM and WHERE: the building blocks of every SQL query
- Filtering, sorting and grouping data
- Aggregate functions: COUNT, SUM, AVG, MIN, MAX
- JOINs: combining data from several tables
- Subqueries: in WHERE and FROM, IN, correlated subqueries and EXISTS
- Window functions: ROW_NUMBER, RANK, DENSE_RANK, LAG, LEAD, running totals and window frames
- CASE expressions and date functions
- Spotting the traps in real data before your numbers go wrong
- All in real PostgreSQL syntax.
HOW YOU PRACTICE
- 8 exercise types: build the query, fill in the blank, predict the output, find the bug, match queries to results and more
- Type your answer or tap the blocks; typed answers are checked by their result
- Practice rounds that bring back the questions you missed, from both courses
- An AI tutor that explains and gives hints without handing over the answer
STAY MOTIVATED
- A daily streak: lessons and the daily question both count
- Badges for lessons, modules, streaks and challenges in both courses
- A certificate for each course you finish, with a public link you can add to LinkedIn
PREPARE FOR SQL INTERVIEWS
The Challenge library holds every past daily question plus extra challenges, from easy to interview level. Filter by level, see what you solved and what you missed.
WHO IT’S FOR
MintQuery is for beginners learning SQL for the first time and career switchers moving into data analytics (SQL Fundamentals), analysts who want practice on messy, real-world data (Real-World SQL), and anyone preparing for SQL interviews (the daily questions and Challenge library). No laptop needed.
WHY MINTQUERY
No hearts, no energy timers, no ads, no waiting hours to continue a lesson. Make mistakes freely: that’s how you learn SQL.
PRICING
MintQuery is free to use, including the daily SQL question, the first three modules of SQL Fundamentals and the first two of Real-World SQL. Premium unlocks every module of both courses, the Challenge library and unlimited AI tutor help, as a monthly or annual auto-renewing subscription.

What's new
- Version: 1.16
- Last Updated:

• Comfortable with SQL? Start with Real-World SQL.
• Faster loading, avatar fixes and fewer update reminders.
Version history6
- Finished a course? Check yourself: one exercise from every module, then another round whenever you like.
Fresher Real-World SQL exercises, clearer lesson openings, tables that show spaces exactly as stored, and tidier labels across the app. - What's new in 1.13
• Interview challenges are tougher in the right way: build each query word by word, with fairer match questions and clearer difficulty levels.
• Share your daily win (the question, never the answer) and your badges.
• Lessons take fewer taps and pick up where you left off.
• Plus smaller improvements and fixes. - - A new look for the Challenge library: search by title or company, and filter by level or what you haven’t tried, right on the page.
- Today’s challenge shows its level.
- Typed queries highlight SQL keywords as you type, and the Tap blocks / Type it switch is clearer.
- Course progress now counts each course on its own, and Profile shows a certificate for each course.
- Fixes in Real-World SQL lessons and exercises. - New course: Real-World SQL. Six modules on messy, real-looking data: missing values, duplicates, joins that count twice. It has its own certificate and badges.
Lessons are easier to read: one text size, centred short screens, and tables shown with their intro. - • New lessons: short tap-through cards with row-by-row walks and animated JOINs
• Type it: write queries instead of tapping blocks. Extra mints, and typos get a hint, not a lost attempt
• Practice more after lessons, plus mixed practice across modules
• Home is now Learn. Real-World SQL course is coming soon
• Download your certificate as a PDF and add it to LinkedIn
• Clearer hints and explanations - Logo. Badges. Avatars.
New look: a fresh MintQuery logo and app icon.
Achievements: earn badges as you learn, see them on your Profile, and share them.
Your Profile now has avatars you can build yourself.
Finished the course? Your certificate has a new design and a public link anyone can use to verify it.
