Hello guys, if you are a computer science graduate or new to the programming world, interested in learning SQL, and looking for some excellent resources, like 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, like tables, stored procedures, etc., and also to store and retrieve data from the database.

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 a 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.
