Instruction

Congratulations! You've completed the whole practice set. We hope you found it challenging and entertaining.

We hope to see you in our next course, How to Insert, Update, and Delete Data in SQL. Also, we encourage you to try out our SQL JOINs course for additional practice. But if you feel confident about your SQL knowledge and would like to try something more advanced, you can move on to Standard SQL Functions and learn how to deal with NULLs and different data types, as well as how to use SQL aggregate functions.
