New Monthly SQL Practice for June 2021!

If you have fundamental SQL skills and know how to write queries, check out our new SQL Practice, available every month on

The June SQL Practice is for people who’ve mastered the basics of SQL. You’ll practice your SQL knowledge helping Jennifer with her dog sitting business – a service that brings together dog owners with people who can care for the pets when the owners are away.

Maybe this is the first time you’ve come across our Monthly SQL Practices. offers one free SQL Practice each month: even-numbered months feature basic-level exercises while odd-numbered months are at an advanced level. Each SQL Practice takes an hour or less and contains 5-10 tasks to help you practice your SQL skills.

Each Monthly SQL Practice features a different business or hobby. We’ve had topics like family trees, language schools, book exchange programs, a job agency, rental cars, astronomy, pizza, movies, clothing retail, and more.

In our June 2021 SQL Practice, you’ll meet Jennifer, a vet who runs a dog sitting service available in different cities. She’s always interested in new business projects, but she wants to see if there are enough potential clients for some ideas she has. Can you help her gather needed information using SQL? It shouldn’t be too hard if you’ve finished our SQL Basics course.

Remember to use the hints, and have fun!
