Union on store procedure

Question

Is it possible to have union on a store procedure and an sql within an application like
create or replace
PACKAGE BODY MyStoredProc AS
PROCEDURE DeparmentName (ColumnA IN VARCHAR2,
wPO OUT curUsr) IS
BEGIN
OPEN wPO FOR
exec MyStoredProcedure 1
union
SELECT distinct departmentName
FROM "schemaNAME".Department d
WHERE d.ColumnA='5000'
END;

Hi Suzie,
please take a look at [url https://forums.oracle.com/forums/thread.jspa?threadID=886365&tstart=0]Understanding Ref Cursors.
The entry "1. What is a ref cursor and how is the data fetched" shows some examples of ref-cursors. How they may work or may fail.
(pointer to data not* container of data, ...)
The next entry "2. How can we use a ref cursor in a SQL query?"
describes how they can be used in SQL.
The last entry "3. What is
the point of ref cursors?" helps when to use or not to use ref-cursors.

Sadly I don't know java.
If you are looking for a "parametrized view" then ...
create or replace
Package Pipeline_Func_Replace
As
   Gcc_Context       Varchar2(32767) := NULL;
   Function    Get_Context Return Varchar2 ;
   procedure   Set_Context(Pic_Context In Varchar2);
   function    Set_Context(Pic_Context In Varchar2) return integer;
End Pipeline_Func_Replace;
create or replace
Package Body Pipeline_Func_Replace
as
   function get_context
   return varchar2
   as
   begin
      return gcc_context;
   end get_context;
   procedure set_context(pic_context in varchar2)
   as
   begin
      gcc_context := pic_context;
   end set_context;
   function set_context(pic_context in varchar2)
   return integer
   as
   begin
      set_context(pic_context);
      return 1;
   end set_context;
end pipeline_func_replace;
create or replace view restricted_emps
as
select a.*
from hr.employees a
where a.manager_id = Pipeline_Func_Replace.get_context; -- the parameter
-- one can set the context with
select Pipeline_Func_Replace.set_context('101') from dual;
-- or with
begin
   Pipeline_Func_Replace.set_context(pic_context => 101);
end;
/... is a possibility.
