SSAS linking a date dimension to an interval columns

问题

I have the following fact table :

ID_Activ  Date_Start   Date_End     ID_session  DayOfWeek   Time_Start  Time_End   
1         01/02/2018   15/02/2018   11          4           08:00:00    10:00:00
2         01/02/2018   15/02/2018   21          4           09:00:00    10:00:00 
3         01/03/2018   15/03/2018   31          2           09:00:00    10:00:00 

I have a conventional dimensions date, and a custom dimension time with hours, minutes and seconds. I would like to slice or dice using these dimensions to get this output:

Date        hour     Count_session
01/02/2018  08       1
01/02/2018  09       2
01/02/2018  10       2
08/02/2018  08       1
08/02/2018  09       2
08/02/2018  10       2
15/02/2018  08       1
15/02/2018  09       2
15/02/2018  10       2
06/03/2018  09       1
06/03/2018  10       1
13/03/2018  09       1
13/03/2018  10       1

we don't show up the null Count_session.

I tried to created a named query with all hours include in date and hours range, but it generate very lot of data! Do you have another solution to linking a dimension with range dates ?

Thank you.

You need to use non empty. Your query would look like this

select [measures].[count_session] on 0,
non empty
([Dim Date].[Date].[Date],[Dim CustomDate].[Hour].[Hour])
on 1
from 
[YourCube]
