The company needs to find the minimum price of a product from each category in order to organize a marketing campaign. They have assigned you this task!

Swipe to start coding

Your task is to obtain the minimum price for each product category. However, to provide customers with options, you need to retrieve only those categories where there are more than 5 different products.

Join two tables, aggregate the data, and use the HAVING clause. At the end, sort the result by the category_name in the ascending order.

Pay attention that in the response, you should have 2 columns: category_name and min_price. So don't forget to set aliases for these columns!

Brief Instructions

  • Retrieve the category.name column and the minimum value of the price column from the category table.
  • Assign the alias category_name to the first column and min_price to the second.
  • Join the product table on the common column category.id = product.category_id.
  • Group the data by category.name.
  • Use a HAVING clause with the condition COUNT(product.name) > 5.
  • Sort the results by category_name.

Solución

SELECT category.name AS category_name, MIN(price) AS min_price
FROM category
JOIN product
ON category.id = product.category_id
GROUP BY category.name
HAVING COUNT(product.name) > 5
ORDER BY category_name ASC;
