The tables on the page are the whole database. Type a SQL-style statement.
The evaluator normalizes whitespace and case, then matches accepted statements for that challenge. It is not a full SQL engine.

Know which table owns the column. Status lives on orders; city lives on customers.

Most revenue questions die if cancelled and unpaid rows leak in.
