In this problem, we solve LeetCode Problem 176: Second Highest Salary.
You are given an Employee table containing employee salaries.
Your task is to find the second highest distinct salary.
If a second highest salary does not exist, return NULL.
Key idea:
✔ Use DISTINCT to remove duplicates
✔ Sort salaries in descending order
✔ Use LIMIT and OFFSET to get the second value
This is a common SQL interview question that tests sorting and subqueries.
