Comment:

Во-первых, насколько я вижу, значение столбца bond в mismatchQuery проверяется на NULL и на пустую строку (''). Но bond имеет числовой тип (int)! Как его значение может быть строкой??? В чем смысл такого сравнения?

alx, исправил в описании

Посмотрел changeset:312/base. Насколько я понял, в столбце bond предлагается хранить ссылку на запись истории (по ключу N). Не следует ли, в таком случае, добавить также foreign key во избежание возможных неконсистентностей?

У себя на сервере в базе изменил. Создал тикет для san: https://trac.adc-line.ru/mc-04/ticket/1252#comment:1
