调用成员过程NULL SELF参数Oracle [英] Calling member procedure NULL SELF argument Oracle

问题描述

我有一个用成员过程insert_obj声明的类型myType.

I have a type myType declared with a member procedure insert_obj.

当我尝试此代码时，出现以下错误:

When i try this code, i get the following error:

declare
   v_obj myType;
begin
   v_obj.insert_obj(1,2,3);
end;

ORA-30625: method dispatch on NULL SELF argument is disallowed

我认为这是因为我没有对象可以调用该方法...

I am assuming this is because i have no object on which to call the method...

但我做不到

select value(a) into v_obj from myTable 

因为表是空的(我想插入其中).

because the table is empty (and i want to insert into it).

那我如何获得一个对象来调用我的方法?

How then do i get an object to call my method on?

谢谢

推荐答案

您可以使用构造函数:

v_obj myType := new myType();
