About this app
Learn SQL in five minutes a day, right on your phone. MintQuery teaches SQL for beginners one idea at a time: a short lesson, then you practice it straight away. Tap blocks to build each query and see the result instantly, with nothing to set up.
Every day there's a new SQL interview question too, adapted from real questions asked at top tech companies. It's free, and it counts toward your streak.
WHAT YOU'LL LEARN
- SELECT, FROM and WHERE: the building blocks of every SQL query
- Filtering, sorting and grouping data
- JOINs: combining data from several tables
- Aggregate functions: COUNT, SUM, AVG, MIN, MAX
- CASE, subqueries, date functions and window functions
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
- 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
- 55 badges for lessons, streaks and challenges
- A completion certificate with a public link you can add to LinkedIn
- Progress saved across devices
