SQL Exercises

Hands-on SQL practice exercises that follow along with the Amigoscode SQL courses. Work through them against your own local PostgreSQL database so you actually write and run the SQL.

How to use this repo

1. Read SETUP.md once to install PostgreSQL and create a practice database.
2. Pick a course, then a section inside it.
3. Open the section's exercises.md and work through each question in psql.
4. Some sections ship with a schema.sql / seed.sql — load them first (instructions in the section README).
5. Stuck? Peek at solutions/ — but try on your own first.

A note on solutions

Solutions currently live in a top-level solutions/ directory so they're easy to find while this repo is still local. Once the repo is initialized with git, they will be moved onto a dedicated solutions branch and removed from main, so students can't accidentally stumble on answers.
