PL SQL How to put many wrappers in one package - sql

Question

reference: How to make a wrapper to return something other than ref cursor
I've got many wrapped functions that are similar to the one below, only they return different columns of course. How can i put them all in one package. because what the examples below does is replace my wrapper package everytime.
I want to know how to remove the global declarations on top so that i can add many in the same package each with different return columns
create or replace package WrapperSample is
type TResultRow is record(
if_type codes.cd%type
,number_infected Integer);
type TResultRowList is table of TResultRow;
function GetADedIcWarningsProv
(
p_hos_id in work_entity_data.hos_id%type
,p_date in date
) return TResultRowList
pipelined;
end WrapperSample;
/
create or replace package body WrapperSample is
function GetADedIcWarningsProv
(
p_hos_id in work_entity_data.hos_id%type
,p_date in date
) return TResultRowList
pipelined is
v_refcur eOdatatypes_package.eOrefcur;
currentRow TResultRow;
begin
v_refcur := YourSchema.getADedIcWarningsProv(p_hos_id, p_date);
loop
fetch v_refcur
INTO currentRow;
exit when v_refcur%NotFound;
pipe row(currentRow);
end loop;
close v_refcur;
return;
end;
end WrapperSample;

Answer 1

you would use one record definition and one table definition per different column set.
create or replace package WrapperSample is
type R_WarningsProv is record(/*...*/);
type T_WarningsProv is table of R_WarningsProv ;
function GetADedIcWarningsProv(/*...*/) return T_WarningsProv pipelined;
type R_OtherFunction is record(/*...*/);
type T_OtherFunction is table of R_OtherFunction ;
function OtherFunction(/*...*/) return T_OtherFunction pipelined;
/* Multiple functions can use the same types as long as
they share the same column definition */
function SomeOtherFunction(/*...*/) return T_OtherFunction pipelined;
end WrapperSample;
