BasicCurious what juicy queries we've got for you this time? Be sure to check this month's challenge!
Welcome to this month’s SQL Practice! New tasks are waiting for you. If you’ve finished our SQL Basics or simply want to test your database skills, this is a good option. Are you ready to solve the business problems in this SQL practice?
In this Monthly SQL Practice, you’ll help Sophie. She manages an online company that publishes and prints books of various genres. She has enlisted you, an SQL specialist, to build queries to help her leverage the database and track various statistics about the company’s performance. What is its printing history? What is the revenue for a particular book? Which authors have signed the most contracts?
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!
