The little shop report.

3 connected exercises

Dataset and schema
orders(id INTEGER, customer TEXT, country TEXT, status TEXT, revenue REAL, refund REAL)

Fictional records. Both revenue and refund use the same arbitrary currency. A second dataset checks that the query is not tied to these numbers.

0 / 3 completed

Choose the first exercise and run the starter query. The dataset is ready.

One optional question

In the past 30 days, how many SQL reports did you finish outside a tutorial?

Clicking sends only your anonymous choice. You can skip this and keep using the tool.

Before you begin.

Is this a SQL simulator?

Queries execute with SQLite in your browser. Passing means your result matches the expected columns, values and order on two small datasets.

Will this get me a job?

This is project practice, not a certification or a promise of employment. Explain your decisions and test further cases before using SQL in production.

Can I see a worked solution?

Yes. Hints and solutions are available. Exported work records whether you used them; completion is not presented as an independent assessment.
