Update Query

Seems like Oracle Doesn't have to the query like this:

update tablea set firstname=tableb.firstname, lastname=tableb.lastname
where tableb.id = tablea.id;

I can have one, it works if it has a match for the two tables, otherwise the two columns updated to null:

update tablea set (firstname,lastname)
=(select firstname,lastname from tableb

  where tableb.id=tablea.id);

Then the following one works, but very ugly:

update tablea set (firstname,lastname)
=(select firstname,lastname from tableb

  where tableb.id=tablea.id)
where exists(
select 'x' from tableb
  where tableb.id=tablea.id)

Any suggestions?
TIA Chris Harvest
