Только я работаю с разрабатываемой БД
Добавляю новые поля к одной из главных таблиц, используя IBExpert
Код: Выделить всё
ALTER TABLE SKLAD_NUMBERS
add PRESENCE SMALLINT default 0;
add MIN_ZAP SMALLINT default 0;
add ZAKAZANO SMALLINT default 0;
add OTLOJENO SMALLINT default 0;
add AVG_ZAK_PRICE TPRICE default 0;
add MIN_INDIV_NACENKA TPRICE default 0;
add MAX_INDIV_NACENKA TPRICE default 0;
/* TPRICE = DOUBLE PRECISION */
Просматриваю содержимое таблицы, вижу что во всех новых полях значения NULL и пишу обновляющий запрос
Код: Выделить всё
update TABLE SKLAD_NUMBERS set
PRESENCE=0,
MIN_ZAP=0,
ZAKAZANO=0,
OTLOJENO=0,
AVG_ZAK_PRICE=0,
MIN_INDIV_NACENKA=0,
MAX_INDIV_NACENKA=0;
Через 3 мин ко мне прибегают с воплями "склад не работает" и уже успели передернуть свич.
Прихожу, FB уже работает, смотрю в логи винды:

Теперь самому стало ясно. Глюкнула моя UDF
и тригер не точно написал
Код: Выделить всё
CREATE TRIGGER SKLAD_NUMBERS_BU FOR SKLAD_NUMBERS
ACTIVE BEFORE UPDATE POSITION 0
AS
begin
NEW.clear_cod = udf_clearskladcod(SKLAD_NUMBERS.dirty_cod);
а надо бы сначала проверку на изменения поля сделать, чтобы не всегда вызывалась
if (new.dirty_cod<>old.dirty_cod) then ...
end
Вопрос пока писал, сам по логам нашол ответ.
Тогда другой вопрос:
А если бы я использовал архитектуру Классик, сам FB бы не умер?
На Линуксе инстанс сервера классики под соединение поднимается xinetd по требованию клиента.
