Help me find customers who ordered a laptop
Based on your schema, join orders → order_items → products, then filter by product name:

SELECT DISTINCT c.customer_name
FROM customers c
JOIN orders o ON o.customer_id = c.id
JOIN order_items oi ON oi.order_id = o.id
JOIN products p ON p.id = oi.product_id
WHERE p.name = 'Laptop';

Why Upskly AI?

Skip the setup. Get to the first problem.

Learning shouldn't start with installation.

Most tutorials begin by asking you to install a database, configure Python, and troubleshoot things that have nothing to do with what you're actually trying to learn.

Upskly AI puts the environment in your browser so you can spend your time writing SQL and Python instead.

✓
Run SQL directly in the browser, MySQL syntax and all.
✓
Run Python with numpy, pandas, matplotlib, and more.
✓
Ask AI about the code you're actually working on.
✓
Save your work instead of starting from scratch.

Built around practice.

This isn't a box where you type one query and disappear. It's a workspace built to let you experiment, get things wrong, and keep going.

Write your query. Run it. Ask for help when you're stuck.

And when you finally get the result you wanted, save it and come back later.

Common questions

Questions about the online SQL & Python compiler

Is the compiler really free?
Yes. You can write, run, and practice SQL and Python without paying or entering card details. Saving your work and AI Assist require signing in.
Do I need to install anything?
No. The compiler runs directly in your browser — no MySQL server, no Python install, no local environment.
Do I need an account?
Not to write and run code. Sign in when you want to save your work, share a notebook, or use AI Assist.
Does the SQL editor really understand MySQL syntax?
The most common MySQL-isms — SHOW TABLES, DESCRIBE, EXPLAIN, and comma-style LIMIT — are translated automatically, so code written for MySQL runs here without rewriting it by hand.
Can I use Python libraries like pandas?
Yes — numpy, pandas, matplotlib, and more are ready to import, and pip install covers most of what those don't.
Is this only for developers?
No. Upskly AI is built to make coding easier to start with — especially for learners who don't want to spend their first hour configuring an environment.
What is an online SQL compiler?
An online SQL compiler lets you write and run SQL queries straight in your browser, without installing MySQL, PostgreSQL, or any database server on your computer. Upskly AI's SQL workspace runs a real embedded database engine with MySQL-compatible syntax, so the queries you write here behave the way they would against a real MySQL database.
What is an online Python compiler?
An online Python compiler runs real Python code in your browser — no local Python install, virtual environment, or package manager required. Upskly AI runs a genuine Python interpreter (not a stripped-down simulation) with numpy, pandas, and matplotlib ready to import the moment the page loads.
Is this a good SQL and Python compiler for beginners?
Yes. There's nothing to configure before you write your first query or script, which is usually the biggest hurdle for anyone starting out with SQL or Python — and AI Assist is there if you get stuck.
Can AI help me debug my SQL query or Python code?
Yes — AI Assist works with the context of your current workspace, including your code, question, and schema, so you can ask for help without copying anything into a separate chat window.
Can I save and share my SQL queries or Python notebooks?
Sign in to save your work, generate a shareable public link, or open a notebook or query someone else shared with you — your work is exactly where you left it next time.
