Hi there,
First please excuse my writing.
I would like some help in the next scenario case.
I have to run a query with "dynamic" dates: from a specific date @RunDate and from max(Date) of the month(@RunDate). If max(Date) is greater than @RunDate and is in the same month.. then the interval will be from max(Date)-17 weeks, else from @RunDate-17 weeks.
here is what i have done so far but i'm stuck.
THANK YOU IN ADVANCE

declare @RunDate as datetime
set @RunDate='09-18-2013'

select
marca,data,nrore FROM tbl_PO_OreSuplimentare as Weeks17
group by marca,data,nrore
having NrOre>0 -- and marca=20000301
and
(
Weeks17.Data > DateAdd(ww,-17,@RunDate) and Weeks17.Data <=DateAdd(ww,0,@RunDate)
OR Weeks17.Data > DateAdd(ww,-17,max(Data)) and Weeks17.Data <=DateAdd(ww,0,max(Data))
)
order by marca, data

do you mean this?


declare @RunDate as datetime
set @RunDate='09-18-2013'

select
marca,data,nrore FROM tbl_PO_OreSuplimentare as Weeks17
group by marca,data,nrore
having NrOre>0 -- and marca=20000301	
and
(
Weeks17.Data > DateAdd(ww,-17,CASE WHEN max(Data) > @RunDate THEN max(Data) ELSE @RunDate END) and Weeks17.Data <=DateAdd(ww,0,CASE WHEN max(Data) > @RunDate THEN max(Data) ELSE @RunDate END)
)
order by marca, data
