Practice SQL on real business data — free, in your browser.
LearnSQL is a hands-on playground where you write queries against realistic sales, A/R, and customer databases, see the exact SQL behind every action, and pull the results straight into Excel or Power BI. No installs. Nothing to break. No login to start.
Opens learnsql.cpetoday.com — our sister site, part of the CPE Today family.
What you can do in the Playground
A visual query builder
Point, click, and watch the exact SQL appear. Every action shows the query it ran, so you learn the language by reading what you just did.
11 real business databases
Northwind, AdventureWorks, Classic Models and more — sales, A/R, customers, inventory. The tables an accountant actually reports on, not toy data.
Straight into Excel & Power BI
Connect the same databases over ODBC or the Web API via Power Query and refresh live. Copy working code in cURL, Python, or JavaScript from any query.
Read-only and safe
A sandbox you can't break — nothing to install, nothing to configure. Free to start, no login for the Playground.
From learning the concept to doing the job
Three steps — and the middle one is free and unlimited.
Learn it in a course
Take a CPE Today data or Power BI course and earn credit while an instructor walks you through the concepts on real accounting scenarios.
Practice it in the Playground
Open LearnSQL and run the same kind of queries yourself against 11 business databases — filtering, grouping, aggregation, joins — as often as you like.
Ship it in Excel or Power BI
Connect the databases over ODBC or the Web API and build the sales dashboard, A/R aging report, or customer analysis you actually need at work.

Is LearnSQL really free?
Yes — the Playground is free and needs no login. Direct database access for Excel, Power BI, and any SQL client comes included at no extra cost with CPE Today courses and materials that use it.
Do I need to install anything?
No. LearnSQL runs entirely in your browser. There's nothing to download and nothing you can break — the sample databases are strictly read-only.
Who is this for?
Finance and accounting professionals who build reports and dashboards, and anyone new to SQL who wants hands-on practice against realistic data instead of abstract examples.
How does it connect to my CPE?
LearnSQL is the hands-on companion to our data and Power BI courses. Learn the concept in a CPE Today session, then practice it live on the same kind of business data — and earn credit for the course.
