How to show row by cell?

Question

MySQL

Hello. I'm not strong in this, so I don't even know how to formulate a question in Google
There is the following code

$you = mysql_query("SELECT id, title, cost, fr, btext, img FROM service ORDER BY id");

Which, as I understand it from the service table, takes cells id title cost fr btext and img
But I added a cell called category to this table in which the numbers are from 1 to 10
Question: How to make it so that all the above listed cells with category = are displayed 4 ?

Answer 1

SELECT
id, title, cost, fr, btext, img, category FROM service WHERE category = 4 ORDER BY id
