oracle中如何将csv转换为表格

问题描述

如何制作一个包，在传入 csv 值时以表格格式返回结果.

How can I make a package that returns results in table format when passed in csv values.

select * from table(schema.mypackage.myfunction('one, two, three'))

应该返回

one
two
three

我尝试了 问汤姆，但这只适用于 sql 类型.

I tried something from ask tom but that only works with sql types.

我使用的是 oracle 11g.有内置的东西吗?

I am using oracle 11g. Is there something built-in?

推荐答案

以下作品调用它作为select * from table(splitter('a,b,c,d'))

The following works invoke it as select * from table(splitter('a,b,c,d'))

create or replace function splitter(p_str in varchar2) return  sys.odcivarchar2list
is
v_tab sys.odcivarchar2list:=new sys.odcivarchar2list();
begin
with cte as (select level  ind from dual
connect by 
level <=regexp_count(p_str,',') +1
)
select regexp_substr(p_str,'[^,]+',1,ind)
bulk collect into v_tab
from cte;
return v_tab;
end;
