The student has not provided any solution to the problem. Without a solution, it's impossible to evaluate correctness, time complexity, space complexity, code quality, or efficiency. To receive proper feedback, the student should submit their attempted solution to the problem.

For future submissions, please ensure you:

1. Write code that attempts to solve the problem
2. Include comments explaining your approach if the solution is complex
3. Test your code with different test cases to ensure it handles edge cases
4. Format your code properly with consistent indentation

The problem appears to be related to SQL (judging by the title), so if that's the case, the solution should include SQL queries that address whatever the problem requirements are.
