Hello Gurus

I am kind of stuck here calculating the datetime difference. 

Here is the problem

Environment: SQL Server 2008

Given:
ResponseDate = '2010-10-02 06:05:13.120"
ShippedDate='2010-10-03 07:08:25.780

Calculate date Difference = (ShippedDate - ResponseDate)
                                         = 1 01:03:12:660   
1 = number of days
01 = Hours
03 = Minutes
12=Seconds
660= Milliseconds


My Query

SELECT  ResponseDate
  ,ShippedDate
,DATEDIFF(day, ShippedDate, ResponseDate) AS DateDifference

This query returns only number of days.
Any gurus here in Sajha. Please help me.

The argument day is not right


Arguments





datepart


Is the part of startdate and enddate that specifies the type of boundary crossed. The following table lists all valid datepart arguments. User-defined variable equivalents are not valid.

select top 100 Shippeddate,Responsedate,
CAST(DATEDIFF(DD,Shippeddate,Responsedate) AS VARCHAR)+' '+CAST(DATEDIFF(HH,Shippeddate,Responsedate) AS VARCHAR)
+':'+CAST(DATEDIFF(MM,Shippeddate,Responsedate) AS VARCHAR)+':'+CAST(DATEDIFF(SS,Shippeddate,Responsedate) AS VARCHAR)
+':'+CAST(DATEDIFF(MS,Shippeddate,Responsedate) AS VARCHAR)

I am using this syntax
DATEDIFF datepart , startdate , enddate )
DATEDIFF(day, ShippedDate, ResponseDate)

This returns the correct number of days. 

If i use other arguments, say Hour 
 
2 days = it's returning 48

I think this cannot be done with a single query. Either a Function() or Stored Procedure.

Have you come across this situation? Or anyone in sajha.
