Don't forget to change the date (@enddate should be the day after the range you want to count)

webex_monthly_stats.sql

use WebEx

declare @startdate datetime;	
declare @enddate datetime;					
set @startdate = '10/1/2015'
set @enddate = '11/1/2015'

--- [TotalAttendee] > 1 (i.e. not someone seeing loggin in to an empty/unstarted meeting)

SELECT COUNT(DISTINCT [MeetingNumber]) as total_meetings_gt1
  FROM [WebEx].[dbo].[RawReports]
  WHERE StartDate >= @startdate and StartDate <= @enddate and [TotalAttendee] > 1

  
SELECT sum([TotalAttendee])as total_attend_gt1
  FROM [WebEx].[dbo].[RawReports]
  WHERE StartDate >= @startdate and StartDate <= @enddate and [TotalAttendee] > 1
