Postgres by Example: A Hands-On Introduction to PostgreSQL
A comprehensive educational resource titled 'Postgres by Example' provides annotated SQL examples for learning PostgreSQL, an open-source relational database. The guide covers foundational topics from basic queries to advanced features like transactions, views, and security. This resource serves as a practical complement to official PostgreSQL documentation for developers seeking hands-on learning.
Postgres by Example is a structured learning guide created by Dariush Abbasi that introduces PostgreSQL through annotated SQL examples. The resource assumes users have PostgreSQL installed and running locally, with the ability to connect via psql. It covers a comprehensive range of topics organized into logical sections: basic querying (SELECT, WHERE, ORDER BY), data types (numeric, text, boolean, dates, UUID, JSONB), data definition language (CREATE TABLE, ALTER TABLE), data manipulation (INSERT, UPDATE, DELETE), joins and set operations, aggregation and grouping, subqueries, functions and operators, indexes, transactions, views, and security features.
