Hi,

I am counting values from database like

Total Calls Made:0:53:29 , Total Calls Received:0:11:25 , Total Call Duration:1:4:54

Total Calls Made:43 , Total Calls Received:5 , Total Call Duration:1:4:54

here how to calculate Average Time Duration:

Total Time Duration / (Total Calls Made + Total Calls Received)
(1995 +20214) / (43+5 )

How can we calculate the Average time(In hrs:mm:ss)

How can we calculate the Average time.

Thanks

Your formula seems correct but you don't have number or calls made or received, instead you have duration of them. Check your data and post again.:-)

To calculate "average duration", convert the duration for each record to milliseconds, then average the number of milliseconds for the group. Once you have that, then add that to a "zero" date and format it as time. In this example, the average milliseconds is the "12345" value:
SELECT CONVERT(VARCHAR(12), DATEADD(MILLISECOND, 12345, 0), 14) AS Duration

Duration
------------
00:00:12:347
