Oracle 10.2.0.4, Супермаг+ 1.026.3 SP7
Отбираю кассовые чеки за один день по дате чека. Около 1800 строк за 3,5 секунды.
Добавляю в критерии отбора номер артикула. Получаю в итоге результат через 9,5 минут. Статистика собиралась как штатными средствами, так и через dbms_stats.gather_schema_stats.
У кого 10-ка, проверьте у себя пожалуйста.

10.2.0.4 24.6 - 3 сек/15 сек. (>10000 строк в первой выборке)
10.2.0.4 26.3сп4 - <1сек,<1сек (400 строк в первой выборке)
10.2.0.4 26.2 - <1сек,<1сек (600 строк в первой выборке)
тебя сп7 именно беспокоит? сп7 у меня нет, а остальное - 9ка...

Получается, TRUNC вызывает фулскан по smcashcheckitems.
В качестве эксперимента убираю TRUNC и добавляю время чека к дате - тормоза пропадают:
