What you’ll learn
This course advances your SQL capabilities within a PostgreSQL environment. You’ll practice writing real queries, applying subqueries, creating and managing views, utilising functions, and handling data with precision - building the real-world skills needed for effective database management and analysis.
Introduction to PostgreSQL
Start by exploring the fundamentals of PostgreSQL, from how its relational database structures work to the purpose of tables, rows, columns, and data types. We’ll guide you through connecting with the psql command-line tool and pgAdmin, then move on to entering, editing, and running SQL commands. By the end of this section, you’ll feel confident navigating the database environment and locating the information you need.
Working with multiple tables
Here you’ll learn how to bring data together from different sources using joins. From combining tables to working with outer, inner, and self joins, you’ll see how relationships between data are managed in PostgreSQL. We’ll also tackle subqueries, showing you when and how to use them effectively, and explore set operators that allow you to merge, compare, and refine datasets for more advanced analysis.
Maintaining and updating data
Develop the skills to keep your PostgreSQL data accurate and up to date. You’ll add new records, update existing ones, and remove data where necessary - all with careful attention to maintaining integrity. You’ll also work with transactions, using commits and rollbacks to manage changes safely, and learn methods for importing and exporting data - enabling seamless interaction between PostgreSQL and external files.
