SQL Practice – April 2022

Can you use SQL to help Olivia manage her hairdressing salon?

Welcome to this month’s SQL Practice! New tasks are waiting for you. If you’ve finished our SQL Basics course or know how to use SELECT, WHERE, GROUP BY, HAVING, ORDER BY and aggregate functions in SQL, this is a good way to test your database skills. Are you ready to solve the problems in this month’s SQL practice?

Can you help Olivia manage her hairdressing salon?

In this story, you've just been hired as an SQL specialist. Are you ready to use your querying skills to help answer the owner’s business questions? Olivia wants to find out which services are the most expensive, how many appointments were made for each day in February, and more.

The answers are hidden in the database; it’s up to you to get them out. Practice your SQL skills and help the shop owners to manage their business!

Hint: In each exercise, you can see a sample of the data. Look in the right-hand menu, under the Database tab.

Have fun!
