Unable to pass parameter in oracle procedure through unix shell script

Question

Hi Experts,
I have oracle procedure where in I have to pass the value of procedure parameter through unix script.
Follwoing is the sample procedure which i tried to exceute from the unix.
Procedure:
create or replace procedure OWNER.PRC_TESTING_OWNER(OWNER IN VARCHAR2) AS
sql_stmt varchar2(1000) := NULL;
v_count number := 0;
v_owner varchar2(100) := owner;
begin
sql_stmt:='select count(1) from '||v_owner||'.EMP@infodb where rownum<=10';
execute immediate sql_stmt into v_count;
DBMS_OUTPUT.PUT_LINE(sql_stmt);
DBMS_OUTPUT.PUT_LINE(v_count);
END;The script which I used is:
Unix
#!/bin/ksh
parm=$1
echo start
sqlplus -s scott@DEV/tiger <<EOF >>result_1.txt
set serveroutput on;
select '$parm' from dual;
exec owner.PRC_TESTING_OWNER('$parm');
EOFThe script is working fine that is i am able to pass to parameter value through unix shell script. :)
But if I want to pass the value of the owner in cursor , I am unable to pass this value through unix.
Following the procedure which i am trying to implement.
create or replace procedure OWNER.PRC_TESTING_OWNER(OWNER IN VARCHAR2) IS
v_owner varchar2(100) := owner;
CURSOR main_cur IS 
  select
  i.ROWID  rid ,
  emp_name,
  deptid
  from v_owner.employee;
CURSOR subset_cur(c_deptid NUMBER ) IS
    SELECT *
      FROM v_owner.DEPT d
      where  d.dept_id=c_deptid;
--##main loop     
FOR i IN main_cur LOOP
      FOR j IN subset_cur(i.deptid) LOOP     
BEGIN
insert into v_owner.RESULT_TABLE
END;
END LOOP;
END LOOP;How can i pass parameter value of the stored procedure through unix script(that is "owner" in this case), when these parameter value is
used in cursor? :(
Can anybody help me regarding the same?
Thanks in Advance !! :D

It's not the parameter in the cursor that is the problem, it's that you are trying to use static SQL for something that won't be known until run time (the owner of the table).
You would need to use something like ...
declare
   l_owner        varchar2(30) := 'SCOTT';
   l_ref_cursor   sys_refcursor;  
   type l_ename_tab is table of scott.emp.ename%type;
   l_ename_array  l_ename_tab;
begin
   open l_ref_cursor for
      'select ename
      from ' || l_owner || '.emp';
   loop
      fetch l_ref_cursor bulk collect into l_ename_array limit 10;
      exit when l_ename_array.COUNT = 0;
      for x in 1 .. l_ename_array.count
      loop
         dbms_output.put_line(l_ename_array(x));
      end loop;
   end loop;
   close l_ref_cursor;
end;
