I'm hoping this is a simple question and I just haven't been able to find the answer in the help file:
Does anyone know of a limatation on primary keys regarding single column keys and how big they can be? It looks like you can easily define a primary key based on one column, but which would be the best datatype for that column? I'm guessing it won't recycle old deleted keys, so at what point would it be unable to create a new primary key value? Or is this even an issue? 8 )

Thanks!
