Sql Oracle从包中的函数返回表

如何在不使用游标的情况下从sql包函数返回表？

我通常喜欢使用包内的所有对象实现流水线函数

这是结果查询：

select *
from table(pkg_example_pipeline.F_PIPELINE_EXEMPLE(0));

create or replace PACKAGE pkg_example_pipeline IS

-- *********** TYPES
TYPE TYPE_EXEMPLE is record (
    id                      NUMBER(10,0),
    name                    VARCHAR2(100),
    date_test               DATE
);

TYPE v_table_exemple is table of TYPE_EXEMPLE;

我经常看到人们为此使用流水线函数。但也可以参阅本文中的前两个链接，了解更简单的表函数。我经常看到人们为此使用流水线函数。但也可以参阅本文中的前两个链接，了解更简单的表函数。
