Calculate DateDiff in SQL in days: Hours: Mins: Seconds format

I am currently working on an SQL script to calculate the difference between two dates that would give me the result in the format DD: HH: MI: SEC. Example: Date 1: 07/30/12 16:00 AM Date 2: 5/4/12 10:31 AM

And the result should be 87: 05: 29: 00

Can you help with a script for this? Sincerely, Arjun

If you are using a SQL server, you can do this:

declare @x int, 
        @dt1 smalldatetime = '1996-03-25 03:24:16', 
        @dt2 smalldatetime = getdate()

set @x = datediff (s, @dt1, @dt2)


SELECT convert(varchar, @x / (60 * 60 * 24)) + ':'
+ convert(varchar, dateadd(s, @x, convert(datetime2, '0001-01-01')), 108)
