PostgreSQL: From Beginner to Intermediate

Blink Data emphasizes writing SQL and working with a database through command-line examples. Creation and data manipulation connect with joins, grouped results and access privileges. It suits learners who want to understand the statements behind a database interface and practice how tables and permissions are defined.

What you will learn

• Create and manipulate data through SQL commands.
• Combine and group information from several tables.
• Explore users and database privileges.

Who this suits

Learners building SQL fundamentals in PostgreSQL; the demonstrations include Windows command-prompt work.

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
