New Monthly SQL Practice for September 2023!

Ready for our new SQL challenge? This time, we have prepared slightly more difficult SQL tasks. Here’s the September SQL Practice course!

This time, you will help Evelyn, the owner of a local art gallery. She would like to gather data to grow her business and has hired you as an SQL specialist to help her out. Which art pieces have not been exhibited? What is the transportation cost for each art piece? The answers are hidden in the database; you just need to find them using SQL functions!

This SQL Practice is at an advanced level and is aimed at those who have finished our SQL Basics and Standard SQL Functions courses or those who otherwise have equivalent knowledge. If you do not feel comfortable working with SQL functions yet, make sure to check these courses out and then come back here for more practice.

Each month, offers a set of interactive SQL exercises for you to practice writing real SQL queries in real-life scenarios. Every Monthly SQL Practice features a different business or hobby. We’ve had practices that feature family trees, a language school, a book exchange, a job agency, rental cars, stars and astronomy, auto repair, baking, pizza, movies, U.S. cities, and more. And these are not just theoretical exercises; you can copy your SQL queries from this practice set, adapt them to your database, and use them in your own projects.

Our SQL practice features basic exercises on even-numbered months and advanced tasks on odd-numbered months. Each SQL practice course includes up to 10 interactive SQL exercises to help you improve your skills. The whole thing takes an hour or less to complete.

As a reminder, this month’s SQL Practice is at an advanced level. Remember to use the hints!
