Learn Procedural SQL by Building a Chess Game in PostgreSQL

Master PL/pgSQL by Building a Fully Functional Chess Game from Scratch with PostgreSQL and Python

What you’ll learn
Build an interactive chess game by combining Python with a PostgreSQL procedural SQL backend.
Create PL/pgSQL functions and procedures using variables, control flow, and built-in functions.
Implement chess piece logic with loops, IF statements, and CASE expressions for all rules.
Connect a Python interface with PostgreSQL to handle game state and player interactions in real time.

Requirements
This course is beginner-friendly, but having some basic programming experience (in any language) will help you follow along more easily.

Description
Are you ready to truly understand procedural SQL by building something meaningful?In this hands-on course, you’ll master PL/pgSQL—the procedural language of PostgreSQL—by building a complete chess game from the ground up. From basic move validation to advanced game mechanics like resurrection and RUA (Check) detection, you’ll learn how to turn SQL into a powerful backend logic engine.This is not just another tutorial about syntax. Instead, you’ll go deep into how procedural SQL works by applying it in a real-world scenario. You’ll also learn how to integrate Python with PostgreSQL to control gameplay, handle moves, and manage game flow in a clean and interactive way.What you’ll build:A chess board using PostgreSQL arraysCustom piece movement functions (pawn, bishop, rook, knight, queen, king)Validation logic for legal movesEnemy king detection and RUA (check) logicResurrection mechanics using stored proceduresA fully playable game loop in Python with dynamic promptsTechnologies and Tools used:PostgreSQL (PL/pgSQL)Python DBeaverVSCodeBy the end of the course, you’ll not only be proficient in PL/pgSQL but also able to apply procedural programming logic to any database-driven application. Whether you’re a developer, data engineer, or database enthusiast—this course will sharpen your backend logic skills through a fun and intellectually rewarding project.

Who this course is for
Beginner to intermediate programmers who want to learn PostgreSQL procedural SQL by building a real chess game with Python integration.
