Question

Hello this is are 2 tables on my db :

I’m trying to get the hotels available for a interval of dates.
In the Rooms table are defined the types of rooms : eg Signe:max_guests=1, Triple : max_guests=3
So for 10 people booking i need something like:

SELECT  SUM(rooms.max_guests * av.RoomAvailable) AS maxPeople 
FROM av AS av INNER JOIN rooms 
ON av.room = rooms.ID AND av.DateofDays BETWEEN '09/28/2012' AND '10/03/2012' 
GROUP BY av.userid
HAVING Count(*) >= 6

but this doesn’t really fit my requirements ..it return me total max_people available/ userID i just need to check if every day for each userID(hotel) there’s >= 10 (max_people) available

Thank yo for your help

Update: if i use this query :

SELECT  av.userid, av.DateofDays, SUM(rooms.max_guests * 

av.RoomAvailable) AS maxPeople 
FROM av AS av INNER JOIN rooms 
ON av.room = rooms.ID AND av.DateofDays BETWEEN '09/28/2012' 

AND '10/03/2012' 
GROUP BY av.userid, av.DateofDays
ORDER BY av.userid, av.DateofDays

i get this:

You have to manually put in the number of days in the count.

WITH cte AS (
SELECT  av.userid, av.DateofDays, SUM(rooms.max_guests * av.RoomAvailable) AS maxPeople 
FROM av AS av INNER JOIN rooms 
ON av.room = rooms.ID AND av.DateofDays BETWEEN '09/28/2012' AND '10/03/2012' 
GROUP BY av.userid, av.DateofDays
HAVING SUM(rooms.max_guests * av.RoomAvailable) >= 10 
)
select cte.userid 
from cte 
group by av.userid 
having COUNT(*) = 6
