Hi Friends,

I have a requirement to display total audio customers & video customers based on some condition from begin time.

If customer names any where comes with abc then it should display audio. If not then as video.

select count(distinct name) as [Audio participant count] from vw_xyz
where endpointname like '%abc%' --- Giving Aduio Count

select count(distinct endpointname) as [Video participant count] from vw_rmxproductionmeetings
where endpointname not like '%abc%' ---- giving Video Count

I want both these two fit in a single query basing on Case statement.

Kindly help me with that dear friends.

Regards,
Vijay

On top of the below.

There is a time stamp column.

I would want to create a SP for the below requirement, where datepart(mm), datepart(dd),datepart(yyyy) would be my input parameters.

So finally if i give the date,month & year as the inputs then for that particular day the count of video participants & audio participants should come.

Hope i'm clear with my requirement.

Try something like:

SELECT SUM(CASE WHEN endpointname like '%abc%' THEN 1 ELSE 0 END) AS Audio, 
SUM(CASE WHEN endpointname like '%abc%' THEN 0 ELSE 1 END) AS Video
FROM vw_rmxproductionmeetings
