EasySQL challenge #42WHERE

Find Products in a Price Range with BETWEEN

Return the products priced from 100 to 500.

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

Find products priced between 100 and 500.

A correct answer returns 23 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 23 rows. This is the output of the model solution on the practice database. The task does not fix a sort order, so your rows may come back in a different order.

What you practise

Returning every column of a table with SELECT *
Filtering rows with a WHERE condition
Filtering a range of values with BETWEEN

Hint and approach

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

Show the hint

Use BETWEEN

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 price is between 100 and 500, both ends included.
Return every column with SELECT *.

Model solution

Checking your session…

What to watch for

BETWEEN includes both ends: a product costing exactly 100 or exactly 500 is returned. It is shorthand for price >= 100 AND price <= 500, and the lower bound has to come first.

BETWEEN. BETWEEN includes both boundary values. On dates stored with a time, the upper bound silently excludes most of the last day.
WHERE. WHERE is evaluated before the SELECT list, so it cannot use a column alias defined there or the result of an aggregate.
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.
