Welcome to the May 2024 SQL Practice! New tasks are waiting for you. If you have finished our course Recursive Queries or otherwise have equivalent knowledge, this is a good way to test your database skills. You should be comfortable using common table expressions (CTEs). Are you ready to solve the problems in this month’s SQL practice?
In this SQL Practice, you will help Jason. He owns a company that makes riding lawn mowers. Jason has hired you, an SQL specialist, to generate detailed reports about the employees at his company. What is the department with the greatest total salary cost? Which employees should he promote?
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!
