No description provided.

The student's solution is completely empty, which means it doesn't address the problem at all. Without any code or approach provided, it's impossible to evaluate correctness, time complexity, space complexity, or code quality.

For a medium difficulty SQL problem, the student should have at least attempted to:

1. Understand the problem requirements (though they weren't provided here)
2. Write a basic SQL query structure
3. Consider potential edge cases in data handling
4. Include comments explaining their approach

I recommend the student:

1. Carefully read and understand the problem statement before attempting to solve it
2. Start with a basic solution and then refine it
3. Test their solution with different test cases
4. Include comments to explain their thought process
