问题
Thanks for helping me out with this one! I apologize in advance for the formatting, but I think it is easy to follow.
Provided is a sample table of data. I need three separate columns created with query language. The running total must go consider the ID and the date.
Running 12 Months - I need sum the value of each ID for rolling 12 months.
Current YTD - Sum the value of each ID for the current year of the date of the value.
Previous YTD - Sum the value of each ID for the year immediately prior to the date of the value.
THANK YOU!

VKP Raised a valid point. If missing months, we would need to fill.
The following will generate your running total columns.
Example
Select *
,Running12 = sum(Value) over (Partition By ID Order By Date Rows Between 11 Preceding and Current Row)
,CalendarYTD = sum(Value) over (Partition By ID,Year(Date) Order By Date)
,PrevCalendarYTD = case when month(date)<>1 then null else (Select Value from @YourTable Where ID=A.ID and date=dateadd(year,-1,A.date)) end
From @YourTable A
Order By ID,Date
Returns
