I have a simple show/hide requirement in an application.

Is it possible to change a single value using sql alone?
Code:
mytable
======
title     | VAR
display | INT // either 1 or 0
So that if the values in my table were:

"My article title"
1

Given that the query contained " ... where title = 'My article title' ... " it could automatically swop that to :

"My article title"
0

and vice versa?

It is early days so I could change the field to "Null" / 1 if that would make things easier?
