I am creating a DB that contains sales data and is structured as such
an_UPC_ID, str_UPC_Description, 1 week sales ending ######
The one week slices of date start Feb 1, 2009 and continue till the end of 2012.
Is there a way to create a query that will select the last column that is NOT NULL?
I am also trying to find a way to create a range of 13, 26 and 52 weeks from the most current which would be the last column with a NOT Null results.
Or should I structure my table differently?
Any help and suggestions are much appreciated
