最近在清理电脑，发现有些东西在电脑里面吃灰，就放上来，看看有没有用得上的。这个函数是在网上看到的，但忘了具体是哪里copy，由于项目需要对这个函数添加了第二个参数

效果展示

select f_getspell('安徽省安庆市怀宁县') from dual;   --ahsaqshnx
select f_getspell('安徽省安庆市怀宁县', 1) from dual;  --anhuishenganqingshihuainingxian
select f_getspell('安徽省安庆市怀宁县', 2) from dual; --an hui sheng an qing shi huai ning xian 

废话不多说直接上代码

create or replace type spell_code as object(spell varchar2(10),code number);

create or replace type t_spellcode is table of spell_code;

--返回拼音与代码的对应关系
create or replace function f_getSpellcode return t_spellcode Pipelined
