Package in package?

Question

Hi,
is there any workaround to implement this?:
CREATE OR REPLACE PACKAGE main_package AS
PACKAGE package_a;
PACKAGE package_b;
PACKAGE package_c;
END main_package;
Thanks

Answer 1

I cannot understand your requirement.
But...
Is this?
<br>
create or replace
packeg aaa
is
procedure main; /* Public procedure */
end;
create or replace
package body aaa
is
procedure aaa1 /* Private procedure */
is
begin
  null; -- any real procedual routine
  /* cannot refer aaa2 */
end;
procedure aaa2 /* Private procedure */
is
begin
  null; -- any real procedual routine
  /* can refer aaa1 */
end;
procedure main
is
begin
  aaa1;
  aaa2;
end;
-- initial package
begin
  null;
end;
<br>
<br>
Or this
create or replace
procedure main
is
-- declare type,cursor,variable for main at here
  procedure sub1
  is
  begin
     null;
  end;
  procedure sub2
  is
  begin
     null;
  end;
begin -- this is main
  sub1;
  sub2;
end;
