EasySQL challenge #49ORDER BY

Sort Products by Price, Lowest First

List every product ordered from the cheapest to the most expensive.

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.

The task

Sort products by price ascending.

A correct answer returns 120 rows with 10 columns: id, name, category, price, cost, stock, sku, status, rating, review_count.

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 5 of 120 rows. This is the output of the model solution on the practice database.

What you practise

Returning every column of a table with SELECT *
Sorting the result with ORDER BY

Hint and approach

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

Show the hint

ORDER BY ASC

Show the step-by-step approach

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

Read from the products table.
Return every column with SELECT *.
Sort the result by price.

What to watch for

ASC is the default, so writing it is optional; many teams write it anyway to make the direction explicit. In SQLite, NULLs sort before every other value in ascending order.

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.
SELECT *. SELECT * is fine for exploring, but its output changes whenever a column is added to the table. Queries that feed a report should name their columns.
