  • We have been given user_transactions table that consist of orders made by eBay customers.
  • We need to query to get top 3 users who have spent at-least $1000 in total.


  • We first need to group all the transaction for each user and perform count of products that user purchased.
  • Once we have number of product purchased by each user , we can filter based amount of money user spend . we can do that using Having clause doing sum(spend).
  • Now all we have to filter top 3 records and we have to sort the records based on count of product and total spend.
  • Here is the the final output.

Final Solution

select user_id, count(product_id) as product_num from user_transactions
group by user_id
having sum(spend) >=1000
order by product_num desc, sum(spend) desc
limit 3
