Here are all the solutions of SQL questions in LeetCode. They are grouped into different folders mainly based on their categories and complexities. The main purpose of the repository is for self-leanring and self-instruction for those who want to learn SQL quickly and those who want to crach SQL interviews. Hence, the instruction and thinking flow for each question will be provided and it is underway. For all the 149 questions until Feb 17, 2021, some of them are similar questions and can be analyzed and solved in the same way, so typically I have 2 things included for each question: 1. what is the biggest challenge for the question. 2. how to analyze and crack it. Stay tuned!
