Get Some PostgreSQL Practice

Many people write to us that they have tried reading SQL books, watching YouTube tutorials, or installing databases on their computer, then started to write 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 requires 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 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. It really pays off.

How do you get this free PostgreSQL course in February 2022?

  • Create a free 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 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 from dribbling and shooting? There are times 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.

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 skills 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.
