some applications use "key generator", sql code in database, create surrogate keys.  oracle , db2 both have "sequence objects" generating keys.  there few articles can found simulating sequence objects in sql server.

when generating fake data use table of numbers or numbers cte generate keys.  suggest total number of methods of generating surrogate keys large -- perhaps infinite -- , subset of ideas.

of course doesn't mean ideas ones, limit might limits of imagination.
