How to pass parameter in Function by using select statement?

Question

Hi,
I got a problem. I cant pass in parameter to function by using select statement. But it can pass in parameter by using 'hardcode' method. How can I solve this problem?
Eg,
select * from table (SplitFunction('HS750020,HS750021')) <<< this work.
but
select * from table (SplitFunction(select LOT_NO from TRACER_SEARCH_SCHEDULE where JOB_ID = '36')) <<< do not work.
Thanks for who try to help. Thanks.

I have try this before. But it not work.here is an example
create or replace type stringlist as table of varchar2(100)
create or replace function splitstring(pstring in varchar2) return stringlist
as
  lstringlist stringlist;
begin
  select regexp_substr(pstring,'[^,]+',1, level) bulk collect into lstringlist
    from dual
  connect by level <= length(pstring)-length(replace(pstring,','))+1;
  return lstringlist;
end;
select * from table(select splitstring('xx,yy,zz') from dual)
create table t(str varchar2(100))
insert into t values('x,y,z')
insert into t values('a,b,c')
select * from table(select splitstring(str) from t where rownum<2)
/If you supply multiple values then it will fail.
select * from table(select splitstring(str) from t)
