Duration Hours: N/A (Live Sessions)

Rating: 5/5 stars (No Decimals, Rounded Up By Eureka)

If you’re all about learning in real-time, you should check out the SQL Essentials course on Edureka. This is another course made to prepare you for SQL from scratch, but this time with online training that happens in real-time.

You also get to access many instructors, not only one, and get a proper certificate that will make your future employment much more accessible.

First, you’re introduced into the database management system, and you slowly start to learn about the objects, the tables, the constraints, etc. Many demos are included, and all of them are related to essential examples of tasks you’ll have to deal with on your own in the future.

However, maybe you’re still not sure whether this course will do you any good. If that’s the case, you can download a more detailed syllabus on the Edureka website and compare this SQL course to some other ones.

Furthermore, you can check the video reviews on Edureka’s website to see whether you can relate to any of the students.

This course provides you with assignments you’ll be able to access for a lifetime, as well as a forum where you can ask questions and help others. This is a great, helpful way to review what you’ve learned.

If you miss a course, you can watch the recording or watch another live session from another instructor. Edureka is particular about the people they employ – all of them have to work in IT for at least ten years!

To sum up, although  Eureka provides a limited amount of reviews and most people (not a lot of them) complain only about the pace, but from what we’ve seen, this is a great way to learn SQL – especially for those who can’t plan their learning journey on their own.

Duration Hours: 9 hours

Rating: 4.7/5 (77,291 ratings)

As the name of this course suggests, you will learn everything about SQL, and you don’t need to worry about the amount of knowledge you’re starting with. Moreover, you don’t need technical experience at all.

Secondly, this course will teach you about SQL in general so that you can apply it to many different fields of your life. You’ll learn about the syntax, the tools, the commands, the analytics, the operators, and much more.

To make sure that you have retained this vital knowledge, you have to pass the tests and the challenges Udemy has prepared.

Every part of this course comes with challenges, and instead of watching others in action, you are the one who learns through examples. Some say there still aren’t enough questions for you to revise the knowledge, but that is a personal preference.

 The author of this course, Jose Portilla,  has been an instructor for quite some time, which is why many reviewers talk about him as clear, understandable, perfectly paced, and experienced. What’s great about this course is that it is often discounted, and you can find it for a low price.

Udemy allows you to check out a preview of the course, so if you’re still worried about whether you’ll like it or not, feel free to dive in.

All in all, this is a very-often-discounted course that provides a great start and introduction for SQL. Although this specific SQL online course won’t give you the material for reviews and alone-work, it is still convenient when it comes to theory.

Which Certification is Best For SQL?

Certifications are a great way to let those who interview you know that you are a serious person looking for a serious opportunity, as you work on your skills even outside of work. However, not all certifications count as important ones.

Some of the best certifications you can get are those by Microsoft and Oracle, but you can’t get them on a budget, and they require a more advanced approach as well.

If you have any chance to get your hands on these, you should do it. Some of the best ones are the IBM Certified Database Administrator, Microsoft SQL Server database certifications, Oracle Certified Professional, etc.

If you can’t, the best SQL certification on a budget comes from Udemy and Coursera, as they are already pretty famous, and the person interviewing you can check what this course is about without much trouble, making it clear what you are capable of after the course.  

How Quickly Can I learn SQL?

Okay, you have gone through the list and found the best course to learn SQL, but you don’t know how to plan because you have no idea how long it takes to master this language. Take into account a few things – the length of your SQL classes, the amount of additional material provided, etc.

Generally, three to four weeks can be enough to have decent knowledge in SQL. You’ll have to devote to it and search for more practical examples and problems on your own, as it won’t take longer than a week to complete the initial course.

Is It Worth To Learn SQL?

SQL classes can take a chunk of time out of your day, so it’s only natural to wonder whether it’s worth it. Sometimes even the best resources for learning SQL cannot motivate us, but you have to look at the bigger picture.

Did you know that some of the world’s most famous databases use SQL? Although this is a fairly old language, it still gives you the insight into the world of databases, and if anything, the courses we named will make it much easier to learn about databases in the future.

It is also worth mentioning that the average yearly pay for an SQL programmer sits around $81,000. If this doesn’t motivate you enough, knowledge and further career upgrades will!

Final Thoughts

We hope that we helped you find the best course to learn SQL for your personal preferences and needs and that you will excel in the future. Good luck!
