Question

I am making a program that auto-runs using windows scheduler. What I’d like to do is set the program to run on the 1st and the 16th of every month. If the program run’s on the 1st. I’d like to have the query run for last month… For example if today was the first of august I would want it to run 7/1/12 – 7/31/12. If I run the program on the 16th I want it to run the query for the current month to the 15th. For example if it were 8/16, I would want the program to run the query for 8/1/12 – 8/15/12. What is the best way to accomplish this? Do I go with 2 seperate programs with the query attaching it to the correct date range? One scheduled to run on the first of every month, and one on the 16th? How would I go about getting the date range and the year as it will depend on which month/year it is run… My query is:

SELECT        Store_Number, Invoice_Number, Invoice_Date, Extended_Price, Warranty_Amount, Quantity_Sold, Invoice_Detail_Code
FROM            Invoice_Detail_Tb
WHERE        (Warranty_Amount > 0) AND (Invoice_Date BETWEEN CONVERT(DATETIME, '2012-08-01 00:00:00', 102) AND CONVERT(DATETIME, '2012-08-05 00:00:00', 102))
ORDER BY Store_Number, Invoice_Date

Answer 1

If you have your query in a view, you might use this:

where
    Invoice_Date between
    (
        case
            when datepart(dd, getdate()) = 1 then dateadd(mm, -1, getdate())
            else dateadd(dd, -15, getdate())
        end
    )
    and
    (
        case
            when datepart(dd, getdate()) = 1 then dateadd(dd, -1, getdate())
            else dateadd(dd, -1, getdate())
        end
    )

UPDATE: Ignoring the time

(I know it looks ugly.)

where
    Invoice_Date between
    (
        case
            when datepart(dd, dateadd(dd, datediff(dd, 0, getdate()), 0)) = 1 then dateadd(mm, -1, dateadd(dd, datediff(dd, 0, getdate()), 0))
            else dateadd(dd, -15, dateadd(dd, datediff(dd, 0, getdate()), 0))
        end
    )
    and
    (
        case
            when datepart(dd, dateadd(dd, datediff(dd, 0, getdate()), 0)) = 1 then dateadd(dd, -1, dateadd(dd, datediff(dd, 0, getdate()), 0))
            else dateadd(dd, -1, dateadd(dd, datediff(dd, 0, getdate()), 0))
        end
    )
