HackerRankSQL

This repository contains my solutions to various SQL challenges on HackerRank. Each challenge is presented as a SQL query problem that tests different aspects of SQL querying and database manipulation. The solutions provided here demonstrate my approach to solving these challenges. Feel free to explore and learn from them.
