What is SQL?
SQL is a declarative query language used to retrieve data from relational databases. It is highly popular across many industries, like data scientists, engineers, digital marketers, and more.
Databases are prevalent everywhere, from websites to banking systems to video games, you name it! High volumes of data produced by billions of users are stored in databases every single day, and to retrieve the valuable data from these databases you’ll need to learn SQL.
In fact, databases are so important that most computer science graduates frequently cite their database class as the class that taught them the most valuable skills for their careers. Alongside Python, it’s the third most popular programming language among professional developers according to StackOverflow’s 2024 Developer Survey.
Hence, learning SQL will give you the ability to do important data work yourself, making you more appealing to any employer out there.
Quick Note about different SQL dialects
As there are many different flavors of database management systems, there too are many different flavors of SQL, each having their own minor differences. But do not worry! The difference is extremely minor, and all SQL dialects share the same common syntax.
Most of the courses in this guide focus you on learning the general SQL syntax and concepts, but I’ve also included some courses that are more focused on one specific flavor. Nevertheless, the SQL you’ll learn in those courses will be transferable to all dialects of SQL.

Best Courses Guides Methodology
I built this guide following the now tried-and-tested methodology used in previous Best Courses Guides (you can find them all here). It involves a three-step process:
- Research: I started by leveraging Class Central’s database with 250K+ online courses and 250K reviews. Then, I made a preliminary selection of the 3,300+ SQL courses by rating, reviews, and bookmarks.
- Evaluate: I read through reviews on Class Central, Reddit, and course providers to understand what other learners thought about each course and combined it with my own experience as a learner.
- Select: Well-made courses were picked if they presented valuable and engaging content and fit in a set of criteria: comprehensive curriculum, release date, ratings and enrollments.
