Match between two row data - mysql

Question

I want to select match count from result where the match count is exact int on a date.
date id_event id_timewindows max_hits
2014-12-16 1 1,2,3 2
2014-12-16 2 2,3,4 2
2014-12-16 3 4 2
2014-12-16 4 5,6 2
2014-12-16 5 7,8 2
2014-12-16 6 9 2
The result what i want is:
date id_event id_timewindows max_hits
2014-12-16 1 2,3 2
2014-12-16 2 2,3 2
Have anybody idea, how to do it in MySQL?
UPDATE:
So i have to explain more. The id_timewindows is not a string attribute, the first one is a result of a view which grouped by id_events and one id_event has multiple id_timewindow.
View result before grouped:
date id_event id_timewindow begin end max_rooms
2014-12-16 1 1 06:00:00 07:00:00 2
2014-12-16 1 2 07:00:00 08:00:00 2
2014-12-16 1 3 08:00:00 09:00:00 2
2014-12-16 2 2 07:00:00 08:00:00 2
2014-12-16 2 3 08:00:00 09:00:00 2
2014-12-16 2 4 09:00:00 10:00:00 2
2014-12-16 3 4 09:00:00 10:00:00 2
2014-12-16 4 6 11:00:00 12:00:00 2
2014-12-16 4 5 10:00:00 11:00:00 2
2014-12-16 5 7 12:00:00 13:00:00 2
2014-12-16 5 8 13:00:00 14:00:00 2
2014-12-16 6 9 14:00:00 15:00:00 2
I use GROUP BY id_event and the id_timewindows is group_concat(id_timewindow SEPARATOR ',')

Answer 1

I found a solution:
SELECT
date,
id_timewindow,
max_rooms,
COUNT(concat(date, id_timewindow)) as counter
FROM `timewindows_reserved`
GROUP BY
date, id_timewindow
HAVING counter < max_rooms
That will result what inverse what i want and i can use it.
date id_timewindow max_hits
2014-12-16 1 2
2014-12-16 4 2
2014-12-16 5 2
2014-12-16 6 2
2014-12-16 7 2
2014-12-16 8 2
2014-12-16 9 2
If I group by date and make a LIST from the id_timewindow then i can recevie the same result as what I wanted, but in inverse logic. Not a reserved timewindows rather the free timewindows. If I reverse this then I can get the result:
SELECT
date,
id_event,
GROUP_CONCAT(id_timewindow SEPARATOR ','),
max_rooms,
COUNT(concat(date, id_timewindow)) as counter
FROM `table`
GROUP BY
date, id_timewindow
HAVING counter >= max_rooms
