Is this possible with mysql?

Question

First of all: sorry for the title, but maybe I will find a better one later.

I asked this some minutes ago, but since I was not able to describe what I want I try it

Answer 1

You need to add a subquery that loads the data from the specified range (eg, 1day/2day/7days) and compares it with the data for the current day.

set @range = 7;
select * from gc_sessions
WHERE user in (SELECT user from gc_sessions
where starttime between subdate(current_date, @range) AND subdate(current_date, 1))

AND starttime > subdate(current_date, 0)

Where @range holds information about the number of days. See your expanded sql fiddle at - http://sqlfiddle.com/#!2/9584b/24
