📊 DataLemur SQL Solutions (MySQL)

This repository contains my solutions to SQL problems from DataLemur, written in MySQL.

🚀 Motivation

Most DataLemur problems and their available solutions are in PostgreSQL. Since MySQL is also widely used in real-world scenarios, I decided to convert and solve these problems using MySQL to better understand the differences between the two.

📂 Contents

• Solutions to DataLemur SQL questions (Free Tier)
• Queries written in MySQL syntax
• Use of CTEs, joins, window functions, and aggregations

📌 Status

This is a work in progress. Currently covering the free set of questions and will continue to add more.

🎯 Purpose

• Practice SQL for interviews
• Understand PostgreSQL → MySQL conversions
• Build a consistent set of MySQL-based solutions

📝 Notes

Some PostgreSQL functions are rewritten using MySQL equivalents (e.g., date handling, intervals, etc.).
