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? -- Grigory Batalov
