sql - 在 SQL 查询中插入日志语句

Question

下面的查询将插入两行，即 999,666，Oracle 将为您提供插入 2 行的日志。

  insert into departments(department_id, department_name, manager_id,location_id)

            select 999,'Administration',200,1700 from dual
union all   select 666,'Marketing'     ,201,1800 from dual

我如何获取像“第999行和666行已插入”这样的日志..通过将日志语句放入查询本身..(用户定义的日志)..就像在java中我们使用log4j对于相同的..

Answer 1

如果您不想修改用于插入的代码，您可以在表上定义一个触发器来记录您的操作。

例如:

create or replace trigger departmentsAfterInsert
after insert
on departments
for each row
begin
    dbms_output.put_line('Inserted department ' || :new.department_id);
end;

这将记录插入操作，无论您如何执行:

SQL> insert into departments(department_id, department_name, manager_id,location_id)
  2              select 999,'Administration',200,1700 from dual
  3  union all   select 666,'Marketing'     ,201,1800 from dual;
Inserted department 999
Inserted department 666

2 rows created.
