我创建了一个After Insert触发器，但是在编译它时出现此错误：

我使用的全局临时表定义为：

一个示例INSERT SQL是：
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);
我不理解“列的定义不正确的错误；据我所知，该列是由“：new”唯一定义的。

答案 0 :(得分：1)
在没有涉及的所有表的完整定义（即s1_city和s1_state_province以及s1_name_and_address的情况下），我只能猜测实际的问题..但是，我猜测是可能您在多个表中都有 add_by 列和 change_by 列，并且对此有所抱怨。
检查您的定义..并通过以下方法弄清您要从组中的哪些列：
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
关于错误的事情，如果您找到它们所指的行，它们将足够准确。
LINE/COL ERROR
--------- -------------------------------------------------------------
35/8 PL/SQL: SQL Statement ignored
84/18 PL/SQL: ORA-00918: column ambiguously defined
Errors: check compiler log
在这种情况下，它从DECLARE开始计数，而不是CREATE ..所以在第35行：
INSERT INTO s1_name_and_address (name_and_address_id,
第84行是：
change_by;
因此肯定是在抱怨change_by列...一点推断表明add_by可能会有类似的问题;）
