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.
