Filter aggregated groups

Return customer_id and order count for customers with more than one order, ordered by customer_id.

Try it yourself

Open a fresh temporary sample shop dataset. Write your query and use Check answer. Checking uses a separate, clean sample so edits to your workspace cannot change the expected answer. Matches are based on this dataset, not a proof for every possible database.

Sample schema

customers(id, name, email, country, joined_at)
products(id, name, category, price)
orders(id, customer_id, ordered_at, status, total)
order_items(id, order_id, product_id, quantity, unit_price)
