I have a view that I'm trying to setup an Index for. One of the select columns for the view executes a user-defined function that has a return value of varchar(250). However, when I try to setup an Index on that column, I see a size of nvarchar(4000). Why is that and will that cause a problem if I continue to setup my index?
