Recently I came across this article and it’s the greatest in explaining the aggregates SO FAR!!

I have strange requirement .

I need to show ranks for all the rows except few in between.
I tried that in using where id’s not in (’1′,’2′)

In this case I’m getting only the rows where id’s not in (1,2)

Is there any way to get those rows as well in the same query ?

Or Do I need to Follow a different approach?

Add a WHERE clause ignoring NULLs, then UNION ALL to add the record that are NULL.

Or, CASE colx WHEN NULL THEN NULL ELSE RANK….

I try to determine the newest Price from multiple Items in a PriceTable. In Oracle, I can do this with ranking functions:

SELECT ItemId, MAX(Price) KEEP(DENSE_RANK FIRST ORDER BY FromDate DESC) AS Price
FROM PriceTable
GROUP BY ItemId

Is it possible to do the same with ranking functions in MSSQL?

Thanks
Martin
