Solve This SQL Challenge

The task

Find products whose name contains "phone".

A correct answer returns 2 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 3 rows of the products table
id	name	category	price	cost	stock	sku	status	rating	review_count
1	Play Kitchen Deluxe	Toys	1786.38	589.51	257	SKU-000001	active	4	57
2	Micro-Cut Paper Shredder 8-Sheet	Office Supplies	907.93	281.46	131	SKU-000002	active	2.5	447
3	4K Dual Dash Camera	Automotive	568.89	204.8	176	SKU-000003	active	4.1	29

The first rows of each table are shown. See how all the tables relate on the database schema page.

Expected output

Expected output of the challenge
id	name	category	price	cost	stock	sku	status	rating	review_count
10	Magnetic Phone Mount Pro	Automotive	1599.08	495.71	411	SKU-000010	active	3.1	176
92	Noise-Cancelling Headphones	Electronics	758.09	416.95	412	SKU-000092	active	3.3	388

The complete result: 2 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
Matching text patterns with LIKE and the % wildcard

Hint and approach

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

Show the hint

LIKE %phone%

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 name contains "phone" (a LIKE pattern with the % wildcard).
Return every column with SELECT *.

Model solution

Checking your session…

What to watch for

LIKE. LIKE without a wildcard is just an equality test. Forgetting the % on one side turns "contains" into "starts with" or "ends with".
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.
