For those that advocate using surrogate foreign keys (non-business key) I have a question. How do you best handle sorting on a foreign key? For example, I have an Ap invoice table with a foreign key to my vendor table (unique integer). I don't have any way to SET ORDER to my vendor field to easily sort my invoices by vendor id. I could bag the integer foreign key in the Invoice table and replace it with the vendor id itself or I could include both the integer key value and the actual vendor id in my invoice table. I like using the integer for speed, ease of use, etc. and although it violates normalization, it may be helpful to have both for sorting. Any suggestions?
