New Monthly SQL Practice for May 2021!

Are you ready to use your SQL skills to write fundamental SQL queries that solve real-world problems? Do it with our new SQL Practice course on LearnSQL.com.

The May SQL Practice is at an advanced level. Our main character this month, Luke, needs your help. You will test your SQL skills by using family tree data created by his brother.

If this is the first time you've come across our monthly SQL Practices, here is some more information about them. LearnSQL.com offers one free SQL Practice each month: at a basic level in the even months and at an advanced level in the odd months. Each SQL Practice takes about an hour (or less!) and contains 5 to 10 exercises that will help you practice your SQL skills.

Also, each SQL Practice features a different business or hobby. Our topics have included apartment rentals, language schools, book exchanges, job agencies, rental cars, stars and astronomy, auto repair, baking, pizza, movies, U.S. cities, clothing retail, and more.

In our May 2021 SQL Practice, you'll meet Luke. He is a student at a university in the U.S. His current class project is to present information about his family tree. Can you help him gather information using SQL? It shouldn't be too hard if you have finished our Recursive Queries course, so don't worry.

Remember to use the hints, and have fun!
