I have a SQL Server table with the following fields:
ID
PRODUCT
ORIGINATION DATE
It contains several different ID's, each with up to 40 PRODUCTs. I need to order the products by ORIGINATION DATE, and then assign a new field with the consecutive number. For example, source data:
ID 1
PRODUCT A
ORIGINATION DATE MARCH 2, 2012
ID 1
PRODUCT B
ORIGINATION DATE DECEMBER 10, 2011
ID 1
PRODUCTO C
ORIGINATION DATE DECEMBER 14, 2011
I need the following output:
ID 1
PRODUCT A
ORIGINATION DATE MARCH 2, 2012
CONSECUTIVE NUMBER: 3
ID 1
PRODUCT B
ORIGINATION DATE DECEMBER 10, 2011
CONSECUTIVE NUMBER: 1
ID 1
PRODUCTO C
ORIGINATION DATE DECEMBER 14, 2011
CONSECUTIVE NUMBER: 2

Select  ID, PRODUCT, [ORIGINATION DATE] , Row_numer() over(partition by ID order by [ORIGINATION DATE]) [CONSECUTIVE NUMBER]
