If I understand your question.....

You can redirect the results of the view into a table like this...

Select * into #Temp from vwSalesResults

Obviously, that won't solve the original problem.

I have a couple of theories on what the problem might be, but would like to see the 2 execution plans and information about the tables.

One question to ask for right now - how often are the indexes on the tables recreated, and how often are the statistics on the tables updated? (i.e. is there an overnight job to reindex, update statistics, etc.)
