SELECT (DATEPART(hh, sod.ModifiedDate) + 
DATEPART(mi, sod.ModifiedDate) + 
DATEPART(ss, sod.ModifiedDate)...

Are you able to reproduce this on a test system? If so, I would do so and review the execution plans after each execution.

One question for you though - how...

My first thought is "why?"... but if that is your odd requirement, and I am understanding your request correctly (INSERT all possible values in hh:mm:ss:ms format), the easiest way I...
