SQL short for Structured Query Language is a standard language for relational databases. Data is stored in relational databases and SQL is used for storing, manipulating, and retrieving that data.
Thus, you will need to learn SQL for communicating with databases no matter which programming language you are using. Another important thing is that SQL can work with almost every kind of database to perform database operations.
Students find it very easy to learn the language as it is just like you are writing English sentences. The advanced concepts though require much logic and functions but you will learn the basics in no time.
In this article, you will be getting some free tutorials and courses for learning SQL. Some of them also provide certifications that you can add up to your resume.
So, let’s get started with the list of free SQL courses and certifications:

It is a beginner-level course which will give you a basic overview of these concepts.
Data Science is the field that uses different methods, processes, and models to extract useful information from data. That data could be structured or unstructured. We recently shared some free Data Science courses to help students. As Data Science is all about data so it requires students to learn SQL.
This course is provided by the University of California on the Coursera platform. This course is specially designed to help students in learning SQL for Data Science purposes. You will be working with different types of data including strings, integers, and characters too. Students will also be learning about some advanced tactics to handle and manipulate data.
Anyone can audit the course content for free but if you need the certificate then you will have to pay charges.
This is a free training course on SQL from Cybrary covering all the basics. They have created video lectures focusing on the core concepts and how learners could be able to apply them in a professional environment.
