Pass multiple values as single input parameter into pipelined function

Question

Hi all,
My need is to pass multiple values as single input parameter into pipelined function.
For example - "2" and "3" are values of input parameter "t":
with data as (
select 1 as t from dual union all
select 2 as t from dual union all
select 3 as t from dual union all
select 4 as t from dual union all
select 5 as t from dual
select * from data where t in (2,3)Is it possible at all?

Answer 1

Not exactly sure, but usually 'multiple values'+'pipelined function' = some IN-LIST related approach?
See:
SQL> create table data as
  2  select 1 as t from dual union all
  3  select 2 as t from dual union all
  4  select 3 as t from dual union all
  5  select 4 as t from dual union all
  6  select 5 as t from dual;
Table created.

  3  AS
  4    l_text  VARCHAR2(32767) := p_in_list || ',';
  5    l_idx   NUMBER;
  6  BEGIN

  8      l_idx := INSTR(l_text, ',');
  9      EXIT WHEN NVL(l_idx, 0) = 0;

11      l_text := SUBSTR(l_text, l_idx + 1);
12    END LOOP;

14    RETURN;
15  END;

Function created.
