вопрос о "новых" значениях в триггере после вставки

Question

Я создал триггер после вставки, но при его компиляции я получаю эту ошибку:

LINE/COL  ERROR
--------- -------------------------------------------------------------
35/8      PL/SQL: SQL Statement ignored
84/18     PL/SQL: ORA-00918: column ambiguously defined
Errors: check compiler log

Определение триггера:

Я использую глобальную временную таблицу, определенную как:

CREATE GLOBAL TEMPORARY TABLE gtt_possible_port_ids
(
   serial_nbr                      number(12,0)                not null,
   port_id                         varchar2(10)                not null,
   CONSTRAINT pk_gtt_possible_port_ids PRIMARY KEY (serial_nbr)
)
ON COMMIT DELETE ROWS
tablespace temp
/

Пример SQL INSERT:

insert into s1_port (serial_nbr, port_name, city_name, state_province_code, country_code, un_locode, name_and_address_id) 
values (2,'Test1','Kitchener','ON','CAN','23456',NULL);

Answer 1

Без полных определений всех задействованных таблиц (то есть s1_city и s1_state_province, а также s1_name_and_address) я могу только догадываться о фактической проблеме ... однако, я предполагаю, что, вероятно, у вас есть столбцы:add_by, а также change_by в более чем 1 таблице, и он жалуется на это.

Проверьте свои определения .. и уточните, какую таблицу вы хотитеэти столбцы в вашей группе по:

    GROUP BY tblPI.serial_nbr,
             :new.port_name,
             :new.city_name,
             :new.state_province_code,
             sc.zip_postal_code,
             :new.port_name,
             :new.country_code,
             ssp.name,
             add_by,     -- need to clarify this column
             change_by;   -- need to clarify this column

Дело в ошибках, они будут достаточно точными, если вы найдете строку, к которой они относятся:

LINE/COL  ERROR
--------- -------------------------------------------------------------
35/8      PL/SQL: SQL Statement ignored
84/18     PL/SQL: ORA-00918: column ambiguously defined
Errors: check compiler log

В этом случае счет начинается с DECLARE .. не CREATE .. поэтому строка 35:

   INSERT INTO s1_name_and_address (name_and_address_id,

и строка 84:

             change_by; 

, поэтомуопределенно жалуется на столбец change_by ... немного экстраполяции указывает на то, что add_by, вероятно, будет иметь аналогичную проблему;)
