What you'll learn
This project-free course will introduce you to the basics of the SQL query language. You do not need to know other programming languages to complete this course. However, it is useful for anyone who wants to learn how to work with data and how databases operate. And what's more, you can use this course as a guide and material for future reference.
You will:
- get to know how to request, update, and delete data using basic SQL operators;

- be able to make queries without using other programming languages;
- find out how to use SQL functions in real-life tasks.
Learn by doing
# 1
Apply knowledge into practice
You already know the theory. Now it's time to code like you do at work—in a professional IDE, with real project constraints, solving problems that actually matter. Welcome to software engineering as it should be.
# 2
Navigate complexity with surgical precision
Most developers waste months learning random concepts without seeing how they connect. Our interactive Knowledge Map fixes this. It shows exactly how every programming concept relates to others, helping you build a structured mental model of coding.
# 3
Copy the best. Then improve.
Here's what top engineers do that others don't: they study other people's code obsessively. When you get stuck on Hyperskill, you can explore solutions published by other developers. See their exact code. Understand their approach. Learn their tricks.
# 4
Code review that actually makes you better
We stripped code review down to what actually matters: does your solution work? Have you handled the edge cases? Is there a cleaner way to write this? Hyperskill acts like a competent reviewer who actually tests your code. Not genius-level analysis, not architecture debates — just solid feedback on making your code better.
