Learn SQL Using PostgreSQL: From Zero to Hero

Will Bunker develops SQL through PostgreSQL and pgAdmin, moving from tables and queries into several more advanced query forms. Views, indexes and common table expressions extend the core work. It suits learners seeking a longer SQL practice resource, with attention to comparing dated interface demonstrations against their installed PostgreSQL tools.

What you will learn

• Build queries with joins and grouped calculations.
• Use constraints, views and indexes.
• Explore recursive queries and common table expressions.

Who this suits

Learners beginning SQL with PostgreSQL; the provider’s last-update date is September 2021, so check setup steps against current tools.

Before you enroll

Run examples in a disposable local database and keep sample data separate from production. Check PostgreSQL and extension versions before following setup instructions. Queries that work on a small example can behave differently as data grows. Inspect constraints, query plans and transaction behavior before applying an approach to a working application.

Put it into practice

Write the same fictional reporting task with a subquery and a common table expression, then compare clarity and the resulting query plans.
