Any way to use cursor values inside other cursor by bulk collect?

Question

hi,
Is there any way to use cursor get_tables value insdide loop get column if i am using bulk collect in both cursors?
I tried a lot but i am nt able to do it.kindly help...
create or replace procedure MULTIPLE_CURSORS_PROC is
v_owner varchar2(40);
v_table_name varchar2(40);
v_column_name varchar2(100);
cursor get_tables is
select distinct tbl.owner, tbl.table_name
from all_tables tbl
where tbl.owner = 'SYSTEM';
cursor get_columns is
select distinct col.column_name
from all_tab_columns col
where col.owner = v_owner
and col.table_name = v_table_name;
begin
open get_tables;
loop
fetch get_tables into v_owner, v_table_name;
open get_columns;
loop
fetch get_columns into v_column_name;
end loop;
close get_columns;
end loop;
close get_tables;
end ;

hi there
Refer this
CREATE OR REPLACE PROCEDURE MULTIPLE_CURSORS_PROC
IS
   TYPE scol IS VARRAY (10000) OF VARCHAR2 (32767);
   v_table_name    scol;
   v_column_name   scol;
   TYPE curtyp IS REF CURSOR;
   get_columns     curtyp;
   CURSOR get_tables
   IS
      SELECT   DISTINCT tbl.table_name
        FROM   all_tables tbl
       WHERE   tbl.owner = 'SYSTEM';
BEGIN
   OPEN get_tables;
   LOOP
      FETCH get_tables BULK COLLECT INTO   v_table_name;
      FOR indx IN v_table_name.FIRST .. v_table_name.LAST
      LOOP
         SELECT   DISTINCT col.column_name
           BULK   COLLECT
           INTO   v_column_name
           FROM   all_tab_columns col
          WHERE   col.table_name = v_table_name (indx);
         FOR ind IN v_column_name.FIRST .. v_column_name.LAST
         LOOP
            DBMS_OUTPUT.put_line (v_column_name (ind));
         END LOOP;
      END LOOP;
      EXIT WHEN get_tables%NOTFOUND;
   END LOOP;
   CLOSE get_tables;
END MULTIPLE_CURSORS_PROC;regards
