how to calculate number of weeks between current date and a receipt date 1

[staceyn]

Hello,
I am using business intelligence development studio 2008 and am trying to figure out how to do a calculation that will return the number of weeks an item has been in stock. The calculation should be determining the number of weeks between the receipt date of an item and the current date. How would I go about creating this calculation?

Thanks,
Stacey

You should be able to use DateDiff:

=DateDiff("WEEK",Fields!ReceiptDate.Value,Today())

You can do it in tour dataset query

Declare @ReceiptDate Varchar(10)

Set @ReceiptDate = '2001-01-01'

Select DATEDIFF(WEEK, @ReceiptDate, Cast(GetDate() AS DATE)) DateInStock

Both of the above answers will give you the number of weekends the item has been in stock not the number of weeks.

Datediff does not calculate the number of periods between 2 dates it gives you the number of period ends.

Example if you use DATEDIFF(YEAR, '2013-12-31', '2014-01-01') it returns 1 because you passed the period end (new years eve) same applies to months, weeks etc.

If you wan the number of complete weeks in stock properly you need to calculate in days then divide by 7 and round down.
