    Steven - Those FUNCTIONs look like nice work. I've saved them off for future analysis. 🙂

    You might want to review the new functions in SQL 2012 dealing with conversion issues first. It might save you unneeded effort :-).

    Noted for future reference because, alas, at this time I must work only with the stone knives and bear skins available in SQL 2008.

    My mantra: No loops! No CURSORs! No RBAR! Hoo-uh![/I]

    My thought question: Have you ever been told that your query runs too fast?

    My advice:
    INDEXing a poor-performing query is like putting sugar on cat food. Yeah, it probably tastes better but are you sure you want to eat it?
    The path of least resistance can be a slippery slope. Take care that fixing your fixes of fixes doesn't snowball and end up costing you more than fixing the root cause would have in the first place.

    declare

    @datetime datetimeoffset = '2012-10-25 00:00:00.000 +04:30'

    select

    case

    when (DATEPART(TZ, @datetime) <> 0 and DATEPART(TZ, @datetime) is not null OR CONVERT(TIME(0),@datetime) <> '00:00:00')

    then 0

    when (DATEPART(TZ, @datetime) = 0 and @datetime <> '')

    then 1

    when (DATEPART(TZ, @datetime) is null)

    then NULL

    end as Precision
