You Want to Learn SQL? You've Come to the Right Place!

It is difficult to list all the benefits of learning SQL. You will work faster and more efficiently with a database, you will no longer be dependent on the IT department, and you will be able to analyze the data yourself and draw appropriate conclusions, among others. Add reporting to this, and you will get a very wide range of cool and useful skills. Maybe you want to change jobs or get a promotion? Learning SQL will definitely help you. Are you ready? Welcome to the LearnSQL.com platform.

LearnSQL.com is an online platform with plenty of interactive SQL courses intended for a wide range of backgrounds in SQL. You will find something for both advanced users and for those who have not written a single SQL query in their life. More importantly, you don't need to install or set up anything on your computer to work on the courses. All you need is an internet connection and a web browser. The exercise databases and the console where you will write SQL lines are on our side.

Each course allows you to interactively practice what you learn. It starts with a detailed explanation of the theory behind the lesson, then we give you an exercise to complete. An interactive console verifies your solution. After completing all the exercises in a course, you take a final quiz to test your knowledge.

Learning Paths

LearnSQL.com courses are organized into learning paths, each designed to develop a specific skill set such as data analysis. You start by choosing a learning path and a SQL dialect (Standard SQL, MS SQL, or PostgreSQL).

You have several options: do the full track, do one or more mini tracks, or take one or more individual courses. The full track allows you to become a SQL master even if you have never coded before, starting from the basics then moving on to more advanced SQL functions and features. Mini tracks develop your skills in a specific knowledge area and level (e.g., basic or advanced).

The table below shows the details of the analytical learning path:
