Пример:
select login, sum(bytes) as bytes from squid_raw_log where time >= $time1 and time < $time2 group by login order by bytes desc

возвращает:

uprav_nt\gvf => 22881837
uprav_nt\ben1 => 8947084
uprav_nt\osa => 4804259
uprav_nt\paa => 4041611
uprav_nt\vds => 3987697
ben1 => 1281094
uprav_nt\dvt => 827048
uprav_nt\kna => 802962
uprav_nt\paa1 => 520926
uprav_nt\rea => 471475
dvt => 117810
root => 1753

где uprav_nt\dvt и dvt - один и тот же человек.
Хочу их складывать ещё привыборке. Как вычленить "uprav_nt\",
если оно есть?
