Course of the Month: SQL Practice Set

Are you starting your adventure with SQL and looking for a place to practice your SQL queries? Or maybe you are preparing for a job interview? I have good news for you. Throughout May, you will have access to our amazing SQL practice course for FREE!

Why is LearnSQL.com giving you a free SQL course? Every month, our users get the opportunity to take one of our great SQL courses for free. This is our tradition. We want our platform users to become better and better at SQL every day. Sometimes, however, reality doesn't cooperate with our personal development plans. That's why we're here with our free SQL Practice Set.

How to Practice SQL

Practicing SQL is nothing more than writing SQL queries and seeing if they run (and produce the expected results). You can possess a whole lot of theory, but without the ability to put it into practice you won't go too far. That's why hands-on SQL exercises are so important to learning this great relational database language. At LearnSQL.com, we believe that learning works best by doing, i.e. solving problems using SQL.

Writing SQL queries is the best way to remember SQL’s syntax and functions. Thanks to our online console, you can see your mistakes immediately. You will know what you are doing wrong and what you need to correct. And those who learn from their mistakes will achieve success!

How can you get this free SQL course in May 2021?

• Create a free LearnSQL.com account or log in if you already have one.
• Start the course. You will have free access to its content until the end of the month.

When learning, many people make simple mistakes that make it difficult for them to achieve their goals. If you want to avoid these mistakes, read Kamila's great article 5 Reasons You Might Fail to Learn SQL.

How Important Is It to Practice SQL?

Practice is one of the most important things in the process of learning any skill, including SQL. The right combination of knowledge and the ability to test it in practice is the key to success. (There are many studies supporting this theory.) This is a much better idea than watching a YouTube lecture or reading a book on a given topic multiple times.

Imagine you are learning to play guitar. If you can read sheet music, scales, and chord layouts perfectly, will you be able to say that you are a guitarist? No! Theory is important, but you also have to start with the main riff of "Smoke on the Water" and then move on to the more difficult songs. The same principle is true for learning SQL.

Practice makes perfect both when it comes to shredding guitar solos and writing an SQL query that contains subqueries and JOINs.

If you’re interested in the science behind effective learning, check out Learning How to Learn on Coursera (it’s free) and the book A Mind For Numbers by Barbara Oakley. Remember, however, that since you found this blog, most likely your original goal was to learn SQL. Get some knowledge about how to learn and then put it into practice on our courses.

Why Choose the SQL Practice Set Course?

LearnSQL.com is the best place to learn and practice SQL. Why do I say that? Thousands of people around the world have trusted us and were very satisfied with our courses. And we aren’t content with our current success; we keep improving our platform, making it easy and convenient to learn on your own schedule.

Why choose the SQL Practice Set in particular? This course is a set of 88 interactive exercises that revisit all the most important SQL topics. You write SQL queries in the online console and immediately check if they are correct. You don't need to install anything on your computer; all you need is the internet and a browser. It is very easy.

If you chose to learn on your own, you’d first have to go through the tedious process of installing databases and SQL writing programs (IDEs), creating tables, finding datasets, etc. If you are a complete beginner in IT, this could be an insurmountable obstacle. We do all the prep work for you; you focus only on learning and practicing SQL.

What SQL Topics Will You Be Practicing?

Our SQL Practice course is divided into five parts. Each part starts with a very brief review of the topic covered and then proceeds to the exercises. The topics covered in the course are:

• Selecting from one table – Review the fundamentals of SQL (SELECT and basic syntax) and practice using WHERE to filter data.
• Aggregation and grouping – Test your knowledge of the GROUP BY and ORDER BY
• JOINs – Practice using different types of JOIN (including LEFT JOIN and non-equi JOINs) to get data from multiple tables.
• Subqueries – Verify your knowledge of simple and correlated subqueries.
• SQL Challenge – Write SQL queries that combine SELECT, WHERE, JOIN, GROUP BY, HAVING, ORDER BY, and subqueries.

This is a great course to review your SQL knowledge or to identify problem areas that you need to work on.

Do you want more? The SQL Practice Set course is part of our SQL Practice track. We created it for users who want to take their SQL queries to the next level. There are two courses in the track: SQL Practice Set and SQL JOINs course (a set of 93 interactive exercises that further explore the power of SQL JOINs).

Who Should Take This Course?

We created this course for people who are looking for SQL tasks to practice. This is something for both programmers who want to improve their database skills and for non-IT people looking for a place to practice SQL. If you are a student preparing for an SQL exam or a jobseeker preparing for an SQL job interview, this course will be perfect. Job hunters can read more about common interview questions in our articles  Complete SQL Practice for Interviews and What SQL Practice Do You Need to Prepare for a Technical Job Interview.

After completing the SQL Practice Set, you will get a certificate. We encourage our users to attach these certificates to their CVs and LinkedIn profiles.
