Oracle对象依赖循环

Question

当我尝试在Oracle数据库中编译项目时,我遇到了问题.为了使它更简单,我有三个对象:2个包(UTILS和TYPES)和1个视图(VIEW).

包UTILS使用包TYPES中定义的类型.包TYPES使用VIEW作为其中一种类型的基础.VIEW在其脚本中使用UTILS包中的函数.当我尝试对其中一个对象进行一些更改时,我无法编译,因为一切都处于无效状态.因此创建了某种对象依赖循环.

请帮我解决这个问题.

例如,无论如何编译下面的代码？每个对象在语法上都是正确的,但它们如何一起编译？

create or replace package my_types is
   type type1 is table of number;
   type type2 is table of my_view%rowtype;
end;
/

create or replace package my_utils is
   function get_1 return number;
   procedure do_something(parameter my_types.type2);
end;
/

create or replace package body my_utils is
   function get_1 return number is
   begin
       return 1;
   end;

   procedure do_something(parameter my_types.type2) is
   begin
       null;
   end;
end;
/

create or replace force view my_view as
select * from dual
where 1 = my_utils.get_1();

exec dbms_utility.compile_schema(user, false);

select object_name from user_objects where status <> 'VALID';

如果您不想/无法拆分包或视图，您始终可以先创建视图的虚拟版本，编译包，然后创建“真实”视图：

create or replace package my_types is
   type type1 is table of number;
   type type2 is table of my_view%rowtype;
end;
/

create or replace package my_utils is
   function get_1 return number;
   procedure do_something(parameter my_types.type2);
end;
/

create or replace package body my_utils is
   function get_1 return number is
   begin
       return 1;
   end;

   procedure do_something(parameter my_types.type2) is
   begin
       null;
   end;
end;
/

create or replace force view my_view as
select * from dual;

exec dbms_utility.compile_schema(user, false);

create or replace force view my_view as
select * from dual
where 1 = my_utils.get_1();

select object_name from user_objects where status <> 'VALID';
