在Oracle数据库中,函数(Function)通常用于返回单个值。然而,如果你需要返回一个表(或一组行),Oracle提供了管道化表函数(Pipelined Table Function)来实现这一功能。管道化表函数允许你逐步返回结果集,非常适合处理大数据集或需要复杂逻辑处理的情况。 1. 解释Oracle函数返回表的概念 在Oracle中,管道化表函数允许函数返...

Oracle函数返回表类型 一.用自定义类型实现 1、创建表对象类型。 在Oracle中想要返回表对象,必须自定义一个表类型,如下所示: Sql代码 create or replace type type_table is table of number; 上面的类型定义好后,在function使用可用返回一列的表,稍后介绍返回多列的 ...
