SQL from Scratch
Go from zero to writing real queries — SELECT, WHERE, JOINs, GROUP BY and more. Every lesson is a written, step-by-step guide with copy-paste code examples and the exact output you’ll see.
What you’ll learn
Course content
One dataset, all the way through
Every example uses the same simple Customers & Orders tables, shown right in the lesson — so you can read the query, see the exact result, then copy the code and run it in your own SQL tool.
