[PHP/MySQL] Query Question

I’m not exactly sure if this is possible and I don’t know where to check to see if it is. :frowning: Anyway, is it possible, using only SQL, to check to see if a row exists, if it does add one to a value on that row, and if the row doesn’t exist make a new row? :q: Or will I have to use PHP to do that?
