Hello guys, I have been sharing some free programming resources e.g. books and courses in this blog for quite some time. Earlier I have shared free courses on Java, Maven, Spring, and Data Structure and Algorithms and today I'll share some of the free online training courses to learn SQL and Database. Why you should learn SQL? Well, it's one of the must-have skills for programmers, application developers, and IT professionals. Like Linux, this is one skill that is going to serve you longer than any other programming language, framework, or library.
The SQL is used to interact with Database Systems like Oracle, MySQL, and Microsoft SQL Server. As per ANSI (American National Standards Institute), SQL stands for the Standard Query language for Relational Database Management Systems.
SQL is one of the important programming languages to interact with various Database Systems for many decades. While many languages that existed two decades ago are extinct now, SQL has always maintained its supremacy in the RDBMS world.
SQL is one of the important programming languages to interact with various Database Systems for many decades. While many languages that existed two decades ago are extinct now, SQL has always maintained its supremacy in the RDBMS world.
Over time, it has only advanced with new features and standards. And it seems to stay that way for years to come.
Most real-world applications use relational data in one way or another and SQL is the query language to work with those data. It allows you to query data to find what you are interested in.
For example, if you are working for an e-commerce giant like Amazon then you can pull out the best-selling items by writing an SQL query. Similarly if you are working as a Data Analysis then you can pull and normalize data using SQL. It's also one of the most required skills for all kind of development and support jobs.
Good knowledge of SQL needs to effectively do your job. It helps you to understand the data, an important part of your application as well as during troubleshooting. Btw, If you don't mind investing a few bucks on your learning then I also suggest you check out The SQL Bootcamp course by Jose Portilla on Udemy. It's a very hands-on and comprehensive course and very affordable too. I bought it for just $10 on the Udemy sale.
In this course, you will learn about writing simple queries including queries related to Dates, String manipulation, Aggregation, etc.
The advanced concepts like joining multiple tables are not covered but you get a good idea of SQL to explore further yourself.
In short, a good SQL course for beginners with absolutely no experience in databases or programming. Apart from DBA and Application developers, BA, QA, and other people who want to learn SQL can use this course.
Recognizing that much of the world's data resides in databases, the curriculum covers SQL comprehensively, from foundational SELECT statements to advanced concepts like JOINs. Participants learn to write essential SQL statements, differentiate between DML (Data Manipulation Language) and DDL (Data Definition Language), and perform operations such as CREATE, ALTER, DROP, and data loading.
The course also delves into working with string patterns, ranges, ORDER, GROUP clauses, and built-in database functions and its also part of IBM Data Science Professional Certificate, one of the popular certificate on Coursera.

This makes this course ideal for beginner DBAs as well as for programmers and application developers who use MSSQL.
That's all about some of the free courses to learn the database and how to write SQL queries. As I said, SQL is an important skill and every programmer should know it.
