(строки, где указаны переменные с символом доллара, формируются динамически, в зависимости от выбранных условий)
Но в серверном коде он как-то обрабатывается дополнительно, потому что там есть листание по страницам. Где это делается в коде я пока не нашел, скорее всего это какой-то общий механизм, вынесенный в отдельную библиотеку.

В веб-интерфейсе информационной системы и в TOAD запрос с такими параметрами выполняется менее секунды.
Если поле bm_action_log_staff_comment я формирую в зависимости от bm_action_log.action_id и определенного параметра, зависящего от текущего пользователя, то в информационной системе этот запрос выполняется очень долго. В TOAD я его повторить пока не могу. |
