问题
I'm currently working on a huge report and need some help on a vital part which I've been on for ironically weeks
I have a report that calculates quantity based on a few things but what im trying to do is when the "PREQuantity" column is null and week of year = 1 then get quanitity from week of year 52 for the previous year the case statement is unfinished i know, but essentially i need the report to force in week 52 of the previous year for the prequantity

i made this change as suggested by @Abhay
,case when Sum(PreQuantity)= null and pos.WeekOfYear = 1 then (Select Sum(PreQuantity) from #presales where WeekOfYear =52 and @year = @Year-1) else SUM(PreQuantity) end as quantity
it didnt work
After Changes
回答1:
I am trying to complete your case statement based on what I understand:
case when Sum(PreQuantity)= null and WeekOfYear = 1 then
(Select Sum(Quantity)= null from Sometable a where a.WeekOfYear =52 and a.year = Year-1)
else null end
Note: Assuming you have a column or can derive a column for year
Sometable can be many tables joined together from where you can calculate sum(quantity)
(Year)-1 will come from your original outer query i.e
FROM pos pos
LEFT JOIN #preweeklystores w ON pos.PosDate = w.[DATETIME]
LEFT JOIN #Product p ON p.ProductCode = pos.ProductCode
AND p.DivNo = pos.DivNo
AND pos.DivNo = w.DivNo
WHERE pos.DivNo NOT LIKE '8__' /* Get rid of IRL Regions */
and w.YearWeek >2013
If you can use alias for tablename as prefix for each column, I would be able to give a exact query. Also, do you have a column for date/year?
