This repository contains my minimalostic SQL explainations and excercises – both general and inspired by the Polish high school final exam in computer science (Matura). No theory, just excercises specifically.

You can also use the informations provided here as a way of help for yourself if you want, since I try to document everything as good as I can. 

###  Repo structure

- **[/exercises](./excercises)**  

  General SQL exercises based on online tutorials, platforms and ChatGPT. I will use this folder to store excercises in which I will practice basic queries like `SELECT`, filtering, sorting, aggregations, joins, and subqueries. Done using **SQLite** and **MySQL**

  

  All excercises

  


  

    

       First excercise 

       Second excercise 

       Third excercise 

    

  

  

- **[/exam-excercises](./exam-excercises)**  

  Tasks modeled after actual high school final exam questions. Most of them involve working with tables such as students, books, orders, etc. Each file contains one task in `.sql` format with clear comments and structured queries.

  This setup allows me to test ideas and reinforce concepts without relying on any online platform.
