It's not clear. Reading the JDBC spec it doesn't seem to say anything
about fetching data from a partially updated ResultSet. Also note that
this doesn't work as you might expect for an update of a regular ResultSet
row.
int i = rs.getInt(1);
rs.updateInt(1, i+1);
// here j will be == i, not i+1.
int j = rs.getInt(1);
We store the pending values in a separate area because it makes things
like cancelRowUpdates or just navigating away from the updated row without
issuing updateRow easy. While I can see the utility of being able to
fetch the updated values, it would complicate the driver, so I'm not
excited about it unless you can point to some documentation that says we
should.
