SQL stash from LeetCode, GFG & HackerRank — synced so you don’t have to sweat it!

💾 SQL Practice Solutions

This repository contains my collection of SQL solutions from various coding platforms:

All SQL problems are organized by platform inside the sql/ directory.

📁 Repository Structure

sql/
├── leetcode/ # SQL problems from LeetCode
├── gfg/ # (Coming soon) SQL problems from GeeksforGeeks
└── hackerrank/ # (Coming soon) SQL problems from HackerRank

Each folder contains .sql files named after the problem title or number, where possible.

🔄 Syncing from LeetCode Repo

The leetcode/ folder is automatically synced from my LeetCode repository, specifically from its database/ folder, using a GitHub Actions workflow.

Whenever changes are pushed to the database/ folder in that repo, the files are automatically copied here to keep things updated.

✅ Usage

You can open and run any .sql file in your preferred SQL environment (e.g., MySQL Workbench, PostgreSQL, or an online compiler like DB Fiddle).

📌 Notes

  • These solutions use standard SQL or MySQL syntax unless specified.
  • Naming conventions may follow problem titles or IDs for clarity.
  • More platforms and categorization coming soon.
