I've got hte below statment that queries a database of call times. What i'm trying to do is display only the details of people who's call times exceed 1hrs. At the moment this is showing everyone. Could some please tell me where i'm going wrong?SELECT extensionname as Consultant, format(SUM([duration]) * 0.000694444444 / 60, 'hh:mm:ss') as DurationFROM callsWHERE DATE = dateadd("d",-1,date()) and duration >= #01:00:00#GROUP BY extensionnameorder by format(SUM([duration]) * 0.000694444444 / 60, 'hh:mm:ss') desc
