Question

我正在尝试在我的DML中使用LOG ERRORS INTO来删除对象。

create table av_parent( id number primary key, name  varchar2(20));
create table av_child (id number primary key, p_id  number, foreign key(p_id) references av_parent(id) );

insert into av_parent values (1,'a');
insert into av_parent values (2,'sa');
insert into av_parent values (3,'af');
insert into av_parent values (4,'ah');

insert into av_child values (11,1);
insert into av_child values (12,2);

BEGIN
  DBMS_ERRLOG.create_error_log (dml_table_name => 'av_parent');
end;
/
select * from err$_av_parent;
delete from av_parent where id=1 LOG ERRORS INTO err$_av_parent ('DELETE') REJECT LIMIT UNLIMITED;

这里，当我删除时，错误消息＆＃34; ORA-02292：违反完整性约束（XYZ.SYS_C00848165） - 找到子记录＆＃34;被插入到日志表中。

我现在在删除时添加一个触发器，但什么都不做

create or replace trigger t_av_parent
before  delete
on av_parent
REFERENCING NEW AS NEW OLD AS OLD
for each row
begin
  null;
  end;

当我使用相同的命令删除时，错误会弹出并且不会插入日志表中。

delete from av_parent where id=1 LOG ERRORS INTO err$_av_parent ('DELETE') REJECT LIMIT UNLIMITED;

感谢任何帮助。感谢

在删除期间将错误记录到引发错误
