Welcome to our March SQL Practice! New tasks are waiting for you. If you've finished our Creating Basic SQL Reports course and have fundamental SQL knowledge, this is a good way to practice your database skills. Are you ready to start the SQL adventure in this month's SQL Practice?
Language skills are very important these days. Some emigrants might not know the language of the country to which they moved. They need to learn the new language from someone who speaks their native language.
Dona's school is a great place to learn a language because she employs teachers with skills in many different languages. For example, you can find a teacher who teaches Spanish to people who speak Polish.
Dona would like to grow her business, but she doesn't know SQL. She has asked you for help. If you've finished our Creating Basic SQL Reports course, you know everything you need to complete this SQL Practice.
You will collect information about courses, students in these courses, cities where they are located, and prices per hour from Dona's database. With this information, you will create reports summarizing the number of students enrolled in these courses, the total revenue of these courses, and the categories of these courses. This information will help Dona's company grow.
Try our SQL Practice to see how you can use SQL to help a language school. (Hint: In each exercise, you can see a sample of the data. Look in the right-hand menu, under the “Database” tab.)
Let's help Dona grow her business!
Practice SQL with our coding challenges! Each month, there’s a new set of exercises to solve with real-time feedback.
