Question
Need to adjust this SQL query to remove all dates up to the first date of sales
You guys helped me build this query, now I have one adjustment that needs to be made. Again, the reason is trending. We have tested this on all products and it's working great, except for new products. Since we're looking at the last 120 days here, it returns 2 months of 0 sales days preceding the actual day we started selling it 2 months ago.
I need to keep the days with 0 sales between regular days, but I want to get rid of all the preceding ones.
Let's say we're excluding all the days starting from the beginning of the month up until the first day of actual sales. From then on, we include everything.
Here's the kicker. Some returning experts might remember that I'm using iDashboards, and the SELECT statement cannot have UDFs or declared tables. This is the reason for the subqueries as tables in my code below. So, I'm not sure if this is even possible, but you guys continue to surprise me!

suppose you have that field in inventorydays table change the query like this and try it.
SELECT d.dates AS InvoiceDate
, i.ItemCode
, SUM(isnull(AR_InvoiceHisto
FROM (select dateadd(dd,datediff(dd, 0, getdate()),-number) as dates from master..spt_values where number between 0 and 120 and type = 'p' ) D
CROSS JOIN (select ItemNumber AS ItemCode, StartDay from InventoryDays) I
LEFT JOIN AR_InvoiceHistoryHeader ON D.dates = datediff(dd,0,AR_InvoiceHi
LEFT JOIN AR_InvoiceHistoryDetail ON AR_InvoiceHistoryHeader.In
AND AR_InvoiceHistoryDetail.It
where d.dates >= i.StartDay
GROUP By d.dates, i.ItemCode
