List the active products with name, category, price and rating, best rated first.

The challenge runs on the SQLabHub practice database (SQLite) and uses the products table. You can solve it in the browser, with nothing to install.

Solve This SQL Challenge

The task

Find all active products, showing name, category, price and rating. Order by rating descending.

A correct answer returns 113 rows with 4 columns: name, category, price, rating.

Tables used in this challenge

`products` 120 rows

id INTEGER (PK) · name TEXT · category TEXT · price REAL · cost REAL · stock INTEGER · sku TEXT · status TEXT · rating REAL · review_count INTEGER

First 3 rows of the products table
id	name	category	price	cost	stock	sku	status	rating	review_count

What you practise

Choosing exactly which columns a query returns
Filtering rows with a WHERE condition
Sorting the result with ORDER BY

Hint and approach

Try the challenge first. Open these only when you need them.

Show the hint

Use WHERE status = 'active' and ORDER BY column DESC

Show the step-by-step approach

How the model solution is built, in the order the database evaluates it:

Read from the products table.
Filter in WHERE: keep the rows where status equals 'active'.
Return only the columns name, category, price and rating.
Sort the result by rating descending.

What to watch for

WHERE runs before ORDER BY, so discontinued products are removed first and only the remaining rows are sorted. Several products share a rating, and their relative order is not defined unless you add a second sort column.

ORDER BY. Without ORDER BY the row order is not guaranteed, even if it looks stable. Rows that tie on the sort columns can come back in any order.
WHERE. WHERE is evaluated before the SELECT list, so it cannot use a column alias defined there or the result of an aggregate.
