Converting MS-Access select * into... to run in Oracle

Question

I have this stored procedure in MS Access:
create procedure foo as
begin
if exists(select name from sysobjects where name='cif_retail)
drop table 'cif_retail'
select * into cif_retail from cif where cstresf=1
end
The above stored procedure checks if table cif_retail exists and if it exists it drops it and then it creates a new table cif_retail with data from cif with the condition cstresf=1.
How can I do the above in Oracle SQL? I tried the following but it comlains about the drop command, and when i remove it, it complains about the create table command too. Please help:
create or replace procedure foo as
begin
drop table w;
CREATE TABLE w AS SELECT * FROM x;
end;
Thanks,
Theodora

You can Also Use
FORMS_DLL
Example
PROCEDURE Create_N_Column_Number_Table (n NUMBER) IS
my_stmt VARCHAR2(2000);
BEGIN
my_stmt := 'create table tmp(COL1 NUMBER';
FOR I in 2..N LOOP
my_stmt := my_stmt||',COL'||TO_CHAR(i)||' NUMBER';
END LOOP;
my_stmt := my_stmt||')';
** Now, create the table...
Forms_DDL(my_stmt);
IF NOT Form_Success THEN
Message ('Table Creation Failed');
ELSE
Message ('Table Created');
END IF;
END;
