Course of the Month: SQL Practice Set in PostgreSQL

Do you know the basics of PostgreSQL but still need some practice? Look no further! Here is a great interactive course, SQL Practice Set in PostgreSQL. Throughout the month of September, you have access to it for FREE!

We at LearnSQL.com believe that to learn a new skill, you need basic theoretical knowledge and, above all, a lot of practice. It's the same with writing PostgreSQL queries – you need a lot of PostgreSQL practice. But sometimes it is hard to find good SQL projects and exercises that are not too difficult for novice users yet are challenging at the same time.

Do you want to take your skills to the next level? Are you preparing for a job interview for a position that requires working with relational databases? You've come to the right place! This course is perfect for your needs.

How do you get this free PostgreSQL course in September 2024?

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

Why Is Our PostgreSQL Practice Course Free?

We have been choosing one of our SQL courses as the Course of the Month every month for some time. A selected interactive SQL course is free of charge for a specific month. This is to help our users who perhaps cannot afford to learn SQL but want to change their situation. Many people have already used the free learning option. Why not join them?

There is no catch! For September, our free SQL course is SQL Practice Set in PostgreSQL.

Get Some PostgreSQL Practice

Many people write to us that they have tried reading SQL books, watching YouTube tutorials, or installing databases and writing SQL queries on their own. However, they say it is difficult to take the next step as a beginner and go full speed with PostgreSQL. They just lack practice.

Most of the PostgreSQL tasks and hands-on courses on the market are either too easy for someone who has already learned the basics of SQL or too difficult (and require knowing very advanced topics). That's why we created this PostgreSQL course.

What does it mean to practice PostgreSQL queries? Simply put, it is writing SQL queries using the knowledge you’ve gained so far. This practice is essential for mastering PostgreSQL, a skill that not only helps you in your current day-to-day work but also allows you to get a new, better job and earn more. Check out my article on hiring people skilled in SQL to see how this skill can pay off

Why Do You Need PostgreSQL Practice?

Suppose you are an athlete – for example, say you play basketball. Do you start training by reading about Michael Jordan and Kobe Bryant? Or do you start by practicing moves like dribbling and shooting? There is a time for biographies and the theory of sports, but the most important things for a beginner basketball player are fitness and ball control. You only get them by practicing.

SQL is similar. You can read great SQL books and watch YouTube tutorials, but there's no substitute for hands-on exercises.

Practice makes perfect, both on the court and in writing SQL queries.

Learning SQL has never been easier!

But why choose SQL Practice Set in PostgreSQL? It contains 88 great interactive exercises. You practice SQL topics from the simplest to the increasingly complex.

What PostgreSQL Topics Will You Practice?

SQL Practice Set in PostgreSQL has five parts. After a short warm-up and reminder of a given topic, you move on to solving the tasks. Don't worry about it being too difficult – you can always use the hints.

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 JOIN, LEFT JOIN, and non-equi JOIN. Check your skill in working with multiple tables.
• Subqueries – Verify your knowledge of simple and correlated subqueries.
• SQL Challenge – Practice PostgreSQL queries that combine SELECT, WHERE, JOIN, GROUP BY, HAVING, ORDER BY, and subqueries.

This is a great interactive PostgreSQL course for reviewing your SQL knowledge or for identifying problem areas you need to work on.

What if you’re hungry for more after you complete the course? The course is part of our SQL Practice in PostgreSQL track. In addition to the SQL exercise set you are reading about, you can also find PostgreSQL JOINs, a course that helps you practice using data from more than one table.

The short answer is “anyone who wants to practice PostgreSQL.”
