About this course.
A hands-on SQL course for professionals who make decisions with data, not just people whose job title is analyst. If you are a manager, founder, product, operations, finance, or marketing lead, this gets you answering your own questions and checking the numbers behind a decision instead of waiting on a report. You write and run real queries in the browser from the first lesson, against one realistic business dataset, and you learn to pair the course with a free AI assistant the way you would at work. No setup, no install.
What you'll be able to do.
- ✓Answer everyday business questions yourself instead of waiting on a report
- ✓Read and sanity-check the numbers behind a decision before you act on them
- ✓Filter, sort, and aggregate data with WHERE, GROUP BY, and HAVING
- ✓Combine tables with INNER JOIN and LEFT JOIN, and find what is missing
- ✓Reach for subqueries, CASE, and basic window functions when a question needs them
- ✓Use a free AI assistant to learn faster and unblock yourself at work
Who this course is for.
- ✓Managers, founders, and team leads who want to pull and trust their own numbers
- ✓Product, operations, finance, and marketing professionals tired of waiting on the data team
- ✓New hires onboarding into a data-driven role who need working SQL, not theory
- ✓Power BI, Tableau, or Excel users who keep hitting the limits of point-and-click

What learners say.
“I stopped raising a ticket every time I needed a number. Running queries right on the page made it click in an afternoon, and now I check things myself before a meeting.”
“Clear, practical, no filler. Pairing it with Copilot in Edge the way the course suggests made the hard parts easy.”
Questions, answered.
Do I need to install a database?
No. Every lesson runs a real SQLite database inside your browser. You press Run and see results. Nothing is installed and nothing is saved between visits.
I am not an analyst. Is this still for me?
Yes. This course is built for professionals who make decisions with data, not for full-time analysts. The goal is that you can answer your own questions and check a number yourself, so you decide faster and with more confidence.
Can I use ChatGPT, Copilot, or Claude while I learn?
Yes, and the course shows you how. There is a short lesson on pairing the course with a free AI assistant as a tutor, with example prompts. AI guesses, so you always run the query and check the result, which is exactly the habit this course builds.
Is this Power BI or Excel specific?
No. This is standard SQL, the language under almost every analytics tool. What you learn here transfers to Power BI, Postgres, MySQL, BigQuery, and more. Small dialect differences exist, but the core is the same everywhere.
How much maths or coding background do I need?
None. If you can write a spreadsheet formula, you can learn SQL. The course starts from the first query and builds one idea at a time.
