SQL INTERVIEW PREPARATION PART-8 How can you find the second highest salary in a table without using the LIMIT clause? You can use a subquery to find the maximum salary that is less than the overall maximum salary. Example:
SELECT MAX(salary)
FROM employees
WHERE salary < (SELECT MAX(salary) FROM employees);
Tip: Explain that this approach can be useful when the LIMIT clause is not supported or if you want to demonstrate proficiency in using subqueries. Share with credits: https://t.me/sqlspecialist Like this post if you want me to continue SQL Interview Preparation Series 👍❤️ Hope it helps :)

SQL INTERVIEW PREPARATION PART-8 How do you find the nth highest salary from a table in SQL? Answer: You can use the LIMIT clause in combination with the ORDER BY clause to find the nth highest salary. Example:
SELECT DISTINCT salary
FROM employees
ORDER BY salary DESC
LIMIT n-1, 1;
Replace 'n' with the desired rank of the salary. Tip: Emphasize the importance of using DISTINCT to handle cases where there are duplicate salaries, and ensure the ORDER BY clause is sorting the salaries in descending order to find the nth highest salary.
