Our readers appreciated the previous post featuring tips, tools, and resources for learning JavaScript. As a result, we’ve created a similar article to help you learn SQL, another programming language.

Like JavaScript, SQL is one of the most frequently used languages. SQL traded its third position with Python in the StackOverflow Annual Survey, in 2021.

Will SQL be relevant in the future? Does it make sense to dedicate time to learning SQL? The answer is an unquestionable YES! SQL will likely become even more relevant in the future.

SQL is a language aimed at helping users manipulate data from relational databases. While data is the currency of the future, SQL seems to have a positive outlook.

What Is SQL?

It sounds weird, but Structured Query Language (SQL) is 48 years old! It firstly appeared in 1974 and was developed by IBM. American National Standards Institute (ANSI) standardized SQL in 1986. It has evolved over the years and fostered an active user community.

SQL handles data, but this data should be stored and manipulated within a management system. That’s why SQL works with a Relational DataBase Management System (RDBMS). The most common RDBMSs are: 

You have likely heard others use SQL and MySQL interchangeably, but they are different. SQL is a query language, while MySQL is a famous RDBMS. Keep in mind that this article will help you learn SQL.

Reasons and Tips to Learn SQL

As with JavaScript, learning SQL isn’t that different. Generally speaking, it will take you longer than expected to get a grasp of SQL. It’s a common tip because too many courses and books feature unfeasible terms to learn a coding language.

With the exception of HTML, you need months to gain a good understanding of a coding language. We refer to the average guy/gal, but you could be an exception, so strive for fast and better results!

JavaScript is widely used in many industries. By default, a front-end or a full-stack developer should have good JavaScript skills. In the case of SQL, you should ask yourself whether you need to learn it and how useful it could be for your job. It’s essential to know if you really need SQL.

SQL is an in-demand skill, so it’s good for your career to have some familiarity with it. As a backend developer, SQL is at least desirable, if not mandatory.

However, the most exciting aspect of learning SQL is that this language is massively used in data manipulation. Everyone needs data, so, more or less, everyone needs SQL.

Taking into account that all the forecasts mention a meteoric rise in data quantity, there will be a high demand for data scientists. Learning SQL secures your position and gives you a competitive advantage in the present, and also in the future.  

Tools to Learn SQL

Learning SQL doesn’t require sophisticated setups, but it does have different requirements than scripting languages. You can use common text editors like Visual Studio Code or Atom.

However, you’d be better off using a dedicated text editor like DbVisualizer. It has a free version with limited functionality that should be enough to get an idea of it.

DBeaver is another widely used tool to write SQL commands. It works with both Mac and Windows, free of charge. The scripts can be neatly organized and exporting them is a matter of just a few clicks.

Valentina and SQLGate are two alternatives that come in both free and premium versions.

Grab your coffee or tea, schedule a few hours a week to learn SQL, and pick up one of the following resources to start your learning journey.

Learning Resources

Fortunately, content creators produce plenty of learning resources for not only newbies but also intermediate to advanced users. You can go with complex resources—a mix of videos, blog posts, and coding challenges.

Alternatively, hundreds of video courses cover all the aspects of SQL. Prefer reading? No problem; many quality books are written to explain the ins and outs of this language.

I hope that the following suggestions will satisfy all your demands.
