?? SQL Question for Data Analysis Interviews
?? Question: "How do you find the second-highest salary from an Employee table without using the LIMIT clause?"
?? Answer:
SELECT MAX(salary) AS Second_Highest_Salary
FROM Employee
WHERE salary < (SELECT MAX(salary) FROM Employee);
Explanation: 1?? First, the subquery retrieves the highest salary. 2?? Then, the main query finds the maximum salary that's less than the highest salary—essentially giving the second-highest salary!
? Pro Tip: For more robust solutions, consider using RANK() or DENSE_RANK() window functions for ranking salaries.
