Best Online SQL Courses for 2021

In this pandemic era, it's no surprise that online learning has become even more popular. To help you narrow things down, I’ve prepared a list of 2021’s 10 best online SQL courses. Find out where you can learn SQL effectively!

The number of online courses on offer – especially in the tech industry – is now impressive. You can find something that suits your interests, competences, and professional ambitions. But how do you know which to choose among the many online SQL courses out there?

Trial versions are helpful in choosing the right course; you can preview the course’s features and content to see if it fits your needs. Some courses are available completely free; others – more extensive and practice-based – are paid or part of a subscription plan.

Last year, Arleta prepared a list of the 5 best online SQL courses for beginners. This year, I have compiled a list of the best SQL learning resources of 2021. Among my choices, you’ll find free and paid courses as well as those certified by global corporations.

Don't be fooled by your own belief that SQL is difficult and you can't learn it. Unless you try, you won't find out for yourself that SQL isn't hard to learn. With a little commitment, you can become an absolute professional in data analysis.

Ready? Let’s go!

Learn SQL to Get a Better Job

If you’re looking for a job, you can strengthen your chances by doing an online SQL course. Knowing SQL is still a very desirable competence in the global labor market! Right now – when data is of particular importance and is collected in terabytes – companies need to find people who can work with data. Knowing the language that lets you effectively communicate with databases puts you in a winning position. And when it comes to relational databases, SQL is the answer.

The creators of online SQL courses place a lot of emphasis on choosing the right learning methods. The most effective courses teach you, entertain you, challenge you, and give you practical tasks – you can become addicted to them. But it's a good addiction, one that can land you a good job and may even allow you to spend your retirement in the Bahamas. According to research conducted by Dataquest, SQL knowledge is requested in almost half of online job advertisements.

By learning SQL, thousands of positions become open to you, and you can choose the companies that suit you best. Even tech giants, despite using proprietary database solutions, use SQL, e.g. to do analytical work. Isn't that motivation enough to take a closer look at online SQL courses?

What Makes a Good Online Skills Course?

A good online SQL course is affordable and user-friendly, even for a technophobe. Flexibility is important, too.

Consider how you learn in a SQL course. Is the course a series of lectures or podcasts? Or is it interactive, with hands-on exercises to solve and real-time feedback? Maybe a blend of the two?

Remember, you don’t need to know all the ins and outs of SQL right away – you can start from the beginning and figure out where you want to focus or apply your skills.

The most important thing is that the learning process should be focused on you, the student. Anything you choose should have an intuitive interface and accessible language that you understand. If you have to struggle with the platform, you’ll have less energy for learning SQL.

So where should you learn SQL? To help you make your choice, I present my list:

Top 10 Online SQL Courses

This specialization includes four individual courses and also teaches you how to make changes to business processes and analyze indicators. This would be helpful if you're running your own business and dealing with data analytics or working in a position where you need SQL to grow.

If you want to learn MS SQL Server and PostgreSQL, you may like this course. Here you will discover the basics and the slightly more advanced features of both SQL dialects.

The course is suitable for beginners. You can use it both on desktop and mobile. In my opinion, it is a bit too expensive; you can find better SQL courses with lower prices.

You should finish the course in three weeks, assuming that you spend 2 hours a week on learning. It's a bit weird that if you complete the tasks faster than the developers intended, you can't move on before the allotted time runs out. Thus, this isn’t truly a self-paced course.

Price: Free access, $49 for the certificate

#1 SQL Basics Interactive Course on
