To create a procedure in a procedure

Question

Hi,
I am trying to do sth like this. I am trying to create a procedure within an anonymmous PL/SQL block and i am basically trying to execute the newly created procedure there.
This example (although wrong) would give a fair idea of what I am trying to do.
set serverout on;
declare
create or replace procedure test_1 is
begin
dbms_output.put_line('gaurav');
end;
begin
exec test_1;
end;
I tried using the 'execute immediate'...dynamic SQL but that doesnt seem to work.
The requirment is that we are processing a document in a SQL and in that document we have a call to a procedure...Generally we compile that procedure before we began processing the document..Now that is not we want to do anymore.
Please suggest a WorkAround.
TIA,
Gaurav

How do i ascertainthat the procedure is always created.It is not a controlled
instance and ppl may create object with the same name.executing dynamically created stored procedures in an uncontrolled environment? Oh boy, your application must be fun.
There are two scenarios:
(1)the existing object is a procedure
(2) the existing object is something else.
In scenario (2) your dynamic creation will fail whatever you do (unless teh object is an index or some such), so all you can do in your procedure is catch the ORA-00955 exception and report it.
In scenario (1) you have a choice. You can either CREATE PROCEDURE or CREATE OR REPLACE PROCEDURE. In the first case you object creation will fail, in the second it will succeeed. Which you choose depends upon whether it is legimiate for the rogue object to have been created by those "ppl".
