Welcome to the March 2024 SQL Practice! New tasks are waiting for you. If you have finished our course Creating Basic SQL Reports or otherwise have equivalent knowledge, this is a good way to test your database skills. You should be comfortable using CASE WHEN, GROUP BY, and aggregate functions. Are you ready to solve the problems in this month’s SQL practice?
In this SQL Practice, you will help Lilia. She owns a genetic testing clinic with various tests available for its patients. Lilia has hired you, an SQL specialist, to generate detailed reports on the performance of her clinic in February 2024. Which tests are the most popular? What do patients choose most often by age?
It is up to you to get the answers to these and other questions using your SQL skills!
Hint: In each exercise, you can see a sample of the data. Look in the right-hand menu, under the tab.
Have fun!
