The question is for me - would have the above code navigate back to the same record? For me it looks like this: (see attached code, it throws no excpetion) The result is with one next(): a b 1 zzz 2 aaa 3 world But i would expect it should be: a b 1 hello 2 zzz 3 world Do i need to requery the ResultSet to get the updated record back? I would have to remember the primary-key of the record i was editing, to be able to jump back to the correct record afterrequery. Which would be going through a loop until i find my record again as i can not assume that the records are ordered by primarykey. What a waste of CPU! Am i supposed to actually do that? Guido
