New Monthly SQL Practice for March 2023!

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

This time, you will help Shelly who runs a coffee shop. Shelly would like to gather some data to expand the business and has hired you as an SQL specialist. Can you help her find the most popular menu items? Can you calculate the total revenue in December 2022? The answers are hidden in the database. You just need to figure out how to get them out using SQL.

This SQL Practice is at an advanced level and is aimed at those who have finished our Creating Basic SQL Reports course or who have the equivalent knowledge. If you don’t feel comfortable using CASE WHEN, GROUP BY, and aggregate functions, make sure to check this course out first and then come back here for more practice.

Each month, LearnSQL.com 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 aren’t 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!
