As a finance analyst, I decided to learn SQL basics to be ready for an interview in the banking sector. I searched for many courses. However, I got lost as most of them were complex and took too long.
Cate's e-book was a great starting point, as it only contained practical examples which I could apply straight away. Within 5 minutes, I was able to write basic functions correctly and easily understood the differences. SQL and coding are complicated, and I really appreciate how simple this e-book is written - exactly what the beginner needs to create basic tables and filter data. Also, you can easily find any function and see how the table looks visually. Definitely, a must-have for a beginner!
