There are a lot of tutorials available that discuss the basics of SQL language and statements, which is beneficial. However, simply learning the syntax often won't take you much further. This is what I experienced when I was learning SQL. I wanted to find quizzes and problems to practice and reinforce the knowledge I had acquired. Unfortunately, finding quality problems to work on can be challenging.
Course Overview
This course will start by introducing the basics of SQL statements through MySQL, one of the most popular databases in use today. If you are a beginner, I highly recommend going through this section. If you are an experienced developer, feel free to use it as a refresher. Practicing while learning these basic statements is encouraged.
Once the basics are covered, you can delve into the more engaging section of solving problems. You will tackle 42 problems categorized into three levels: basic, intermediate, and advanced. This progression ensures you understand the foundational tools before moving on to more complex issues.
SQL questions are almost always a part of interviews for developer positions. Commonly, they involve challenges like joining tables, which can be difficult for newcomers to SQL. There is a lack of quality practice material, and this course aims to address that gap.
How to Use This Course
Solve the problems yourself to consolidate your knowledge. While you can follow the lessons to go through each problem, it's important to return and solve the problems independently. To combat memory loss and convert short-term memory to long-term memory—especially before interviews—revisit these problems regularly. Not every keyword or statement is covered in this course, but you can always refer to tutorials and documentation as needed. The essential part of this course is the practical problems and your process of solving them. I'll provide the problems, but it's up to you to engage with them fully.
