INVENTORY.partid, INVENTORY.description, (INVENTORY.reorderpnt - INVENTORY.stockqty)
 

Display the part id and description for all parts where the stock quantity is less than the reorder point.   I have this one working:

SELECT PartID
     , Description
FROM INVENTORY
WHERE Stockqty <= Reorderpnt;

How can I modify  the query above to get the below :

For each part where this is true also display the amount that the stock quantity is below the reorder point. Display the parts in descending order of the computed difference.

As an aside...

Not being judgemental or anything, but I get the feeling from the questions you're asking that you're either following some form of teach yourself SQL book or this is a class assignment.

While I don't mind helping you with the solutions you need (that is what the site is for, after all), if it is a class related assignment, it is imperative that you fully understand why these things work the way they do - there's no EE about when it's time to be examined on what you know :)

The help available on SQL Syntax in Books Online and on the internet in general is exhaustive.

Make sure you have a good understanding of the concepts by doing a lot of reading.

Like I said, not trying to pass judgement, want to make sure you are getting everything out of whatever it is you're doing.  Understanding the results is just as important as the results themselves.
