Well on my database primary keys are usually not changed by an update. So your example would look like this:

anonymous wrote : 
  | pk 	key 	name
  | 1	1 	johm	(this is an insert)
  | 1	1 	john	(this is an update)
  | 2	2 	Pat	(this is an insert)
  | 

If you want a column that increments on updates look at the @version annotation or use a trigger.

Felix
