Please introduce the necessary queries from the perspective of a data analyst. It was very helpful for SQL beginners and me who is preparing for the coding test, such as the principles of writing SQL statements and how to divide problems. Thank you!!

[Practice Makes Perfect] Intermediate SQL for Data Analysis

How to break down a problem! That's a cool phrase. I thought it would be helpful to explain the problem step by step if I showed you my thought process, and I think you did a good job of explaining it. Thank you for the encouraging review.
