update some-more quarrel atomically

i need govern name following transform rows resultset an atomic way.

the formula i am controlling looks (simplified):

stmt = con.createstatement(resultset.type_scroll_sensitive, resultset.concur_updatable);
rs = stmt.executequery("select ...");

while (rs.next()) {
    (conditions_to_update) {
        rs.updatestring(...);
        rs.updaterow();
    }
}

• can i pledge updates going executed atomically ? not, i assure ?


• what happens any slight altered database quarrel updating around updaterow() ? there any proceed close rows resultset ?
