Top 5 SQL and Database Courses to Learn Online in 2020 - Best of Lot

Hello guys, if you are a computer science graduate or new into the programming world, interested in learning SQL and looking for some excellent resources, e.g. books, courses, and tutorials to start with, then you have come to the right place. In the past, I have shared some of the best SQL books and tutorials, and today I am going to share some of the best SQL and database courses to learn and master this useful technology. If you don't know what SQL is and why you should learn it, let me give you a brief overview of SQL for everyone's benefit. SQL is a programming language to work with a database. You can use SQL to create database objects, e.g. tables, stored procedures, etc. and also to store and retrieve data from the database.

The SQL is one of the most essential skills for any programmer, irrespective of technology, framework, and domain. It's even more popular than a mainstream programming language like Java and Python, and it definitely adds a lot of value to your CV.

SQL allows you to play with data, the most valuable asset of today's world. By learning SQL, you can get answers to your question. For example, if you are a course creator for Udemy, a popular online course platform, and want to know which course is the best seller and which course is not selling at all.

It can help in troubleshooting as well as reporting. Also, SQL is very stable technology, it's been around for years, and it will be needed in the future. This means any investment you make in learning SQL will also serve you for a long time in your career.





5 Courses to learn SQL and Database Online

In the past, I have also shared some free SQL courses which my readers liked, but the feedback was that they want more comprehensive and in-depth material, and that's why I am coming with this list of best SQL and database courses for both beginners and experienced programmers.

In this list, I have included some of the best SQL and Database courses from Udemy and Pluarlsight, two of the leading place for online courses.

These courses will teach you SQL from ground zero. Most of them don't even need a pre-requisite as long as you know how to operate a computer and download stuff from the internet, which you know, and that's why you are reading this article.



1. The Complete SQL Bootcamp

This is an excellent SQL course for beginners. The course starts from scratch and doesn't require any previous programming skills or experience.

As the name suggests, the course is inspired by Bootcamps and focuses on intense learning. It's also a comprehensive course and explains every single concept by using slides as well as live coding.

The author uses PostgreSQL for demonstration purpose, which is both free and open source. It also comes with a GUI tool called PgAdmin, which makes it easy to work with the PostgreSQL database.

Even though the author uses PostgreSQL, all the concepts you learn in this book are applicable to other major databases, e.g. Oracle, Microsoft SQL Server, and MySQL.

Another plus point of the course is an instructor who is very enthusiastic and detailed in his approach. Overall a great course to start learning SQL from scratch. Particularly for beginners.

2. SQL for Newbs: Data Analysis for Beginners

This is another awesome and fun course to learn SQL for beginners. I really enjoyed watching this course not just for content but also for the positive energy of both instructors David and Pete.

It's entertaining watching them discussing and explaining SQL concepts. I know SQL is interesting, but they make it even more exciting. It's like old college days with some friends always jumping and doing stuff which makes you laugh but at least help remove boredom from the class.

Coming to the content, as the name suggests, it's a beginner course, but you will learn all essential concepts, e.g. creating a database, tables, stored procedures, using SELECT, INSERT, UPDATE and DELETE statements.

They use the MySQL database in this course, which is the most popular, open-source database, and you can download that for free. They have a section for downloading and installing MySQL database too.

After basics, you will learn some non-trivial stuff, e.g. GROUP BY operator and aggregate functions, connecting tables, joining on multiple conditions, and dealing with other SQL operators and functions.

The best part, of course, is that it has got brainbuster and exercise to test your SQL knowledge, which is key to build data sense you need to work with relational database and SQL.






3. SQL & Database Design A-Z™: Learn MS SQL Server + PostgreSQL

This is another great course to learn SQL in depth. It covers almost all the topics an application developer should know about SQL.

In this course, you will learn about creating basic SQL queries, different types of joins, e.g. right and left join, inner join, outer join, cross enter, self-join, etc.

The course also explains advanced concepts, e.g. indexes, and writing SQL queries with multiple tables and joining them together to produce a meaningful report.

You will also explore Database design concepts, e.g. normalization. The course has an entire section explaining Normalization and various standard forms, e.g. 1NF, 2NF, 3NF, BCNF, etc.

The course uses both Microsoft SQL Server and PostgreSQL, and the best part of the course is that it focuses on enhancing your Data Analytics skill with real-world Data Science exercises.

If you are interested in Data Science and want to become a Data Scientist, then a good knowledge of SQL will go a long way, and this course is a great place to start with.

5. 200+ SQL Interview Questions

This is an excellent course to learn SQL from interview point of view. If you are preparing for your first job interview or next job, you can expect a lot of SQL questions on the interview. It's an important skill, and that's why many interviews focus on SQL along with Data Structure and algorithms.

By taking this course, you will not only prepare well for your next interview but also learn a lot about essential SQL concepts. For example, if you just watch the preview of one chapter, which discusses how to tune SQL query or how to find and explain the execution plan, you learn a lot.

I am a particular fan of learning from interview questions as they encourage me more and bring curiosity, and if you are like me, you will find this course immensely helpful. I have bought this course for just $10.99 USD last year and still enjoy it a lot.


200+ SQL Interview Questions

It's also a perfect companion for Joe Gekko's SQL puzzlers book, which is an excellent read in itself. An interesting SQL query and puzzle book, which is you must read if you haven't learned it yet.


That's all about some of the best online courses to learn SQL and Database fundamentals. These are excellent SQL courses for both beginners and experienced programmers who don't know SQL.

Thank you for such an informative post. I've no prior programming knowledge. Thinking of starting with SQL and Python. I'm from the commerce background with very little knowledge about these skill sets . I was wondering if you could give me some advice.
