Selecting multiple records based maximum dates using Row_Number().
Is it possible to take this script and expand it to allow the selection of the last cost, quantity and date from other vendors? What I am trying to get is the last values from a selected vendor. What I then want to add is the same last information from any other vendors for the same item.
DECLARE @BEGVND CHAR(21)='AAA'
;WITH X
AS
(SELECT ROW_NUMBER() OVER (PARTITION BY ITEM_NUMBER ORDER BY ITEM_NUMBER,LAST_QUOTE_DAT
FROM IVPLVLVN)
SELECT *
FROM X
WHERE X.VENDOR_NUMBER=@BEGVND AND X.RN =1
I have attached a sample dataset. The desired output would be
PART01,P01,5.00,1,5/20/201
PART01,P02,330.00,15,12/15
PART02,P01,295.00,32,5/13/
PART02,P02,285.00,2,2/7/20
PART03,P01,21.00,6,12/31/2
PART03,P02,17.00,12,12/31/
So there will always be one for the selected vendor but there could be as many as found for all the other vendors who have quoted a cost. All records must reflect the most recent quoted cost.

dont you have any INPUT DATE, or DATA ENTRY DATE in your tables?, that would be a lot better than trying to use rownum
Seems like you should be able to add VENDOR_NUMBER to the partitioning:
(SELECT ROW_NUMBER() OVER (PARTITION BY VENDOR_NUMBER, ITEM_NUMBER ORDER BY ITEM_NUMBER,LAST_QUOTE_DAT
FROM IVPLVLVN)
(SELECT ROW_NUMBER() OVER (PARTITION BY VENDOR_NUMBER, ITEM_NUMBER ORDER BY ITEM_NUMBER,LAST_QUOTE_DAT
FROM IVPLVLVN)
I have tried several variations without success. This script will be embedded in an SSRS report. The user will supply the desired vendor ID so any items that come from that vendor will be listed as the first row per item. Any subsequent rows would be for the same item from other vendors but ONLY be the most recent Last_Quoted_Cost.
DECLARE @BEGVND CHAR(21)='U07'

AS
(SELECT ROW_NUMBER() OVER (PARTITION BY VENDOR_NUMBER_IVVQ,ITEM_NU
FROM POWMATQP..IVPLVLVN T1)

I believe you need more than a single row number calculation. One for the filtering, and another for the ordering. For filtering just concentrate on getting the most recent rows regardless of vendor.
For ordering the result rows partition by item number then in order by using a case expression so that if the vendor matches the parameter set that to 1, else 2. Then fine-tune the remaining order by the vendor.
Filtering by rn=1 should be all you now require, then use the second calculation to assist ordering of the result

Did you try Scott's suggestion? That should solve your need based on your sample data and expected result.
It doesn't harm but you can remove ITEM_NUMBER in the ORDER BY clause.

Maybe I am not understanding, but seems fairly straightforward.
If you want to see the seected vendor at the top of the list, then you could do something like : CASE when VENDOR_NUMBER_IVVQ = @BEGVND then 1 else 2 end as VSORT and use that in the Order By. Can also check VSORT in the final WHERE clause : WHERE X.RN =1 and VSORT = 1 -- etc
or if wanting other venfors but only if the parameter one exists : where RN = 1 and (VSORT = 1 or (VSORT = 2 and exists (select null from x where vsort = 1)))
Does that make sense ?

OK, we are real close. Scott's version only gives me records for the specified vendor and PortletPaul's version gives me all items. If the item does not come from the specified vendor I want no records to be returned. If the item does come from the specified vendor, I want the most recent record for that vendor and then the most recent record for all other vendors that provide that part. You have all been most helpful. I will tweak this some more in the morning.
I discovered that many rows have blanks for the item and/or vendor number. My revised script looks like this now.

Here is a more complete dataset. The 'DoNotWant' illustrate records to not be included. Since none of them come from U70 I want none of them. The 'WantThese' tabs shows the ones I do want. U70 for one and then the most recent of each vendor, as marked.

This version is very close. However, look at the file sent with this. Part 199D3980G001 should not be included as it does not come from U07.

Can you try this?

Simple, just add the item_number_ivvq test to the EXISTS e.g.
