10 Best Courses to learn SQL in 2023 [UPDATED]
My favorite online courses to learn SQL and Database for beginners in 2023 with PostgreSQL, MySQL, Oracle, and SQL Server examples.
Hello folks, if you are a programmer, developer, IT professional, Data Scientist, or software Engineer interested in learning Databases and SQL and looking for the best resources like best books, courses, and tutorials — to start with, then you have come to the right place.
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 store and retrieve data from the database.
SQL is one of the most important skills for any programmer, irrespective of technology, framework, and domain. It is 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, which is the most important asset of today’s world. By learning SQL, you can get answers to your questions. For example, you can use SQL 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 and has 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.
