How we can create a table in PL/SQL block. Insert records into it??? is it possible by some procedure or function?? please give example...

CREATE OR REPLACE PROCEDURE ddl_create_proc (p_table_name IN VARCHAR2)
AS
l_stmt VARCHAR2(200);
BEGIN
DBMS_OUTPUT.put_line('STARTING ');
l_stmt := 'create table '|| p_table_name || ' as (select * from emp )';
execute IMMEDIATE l_stmt;
DBMS_OUTPUT.put_line('end ');
EXCEPTION
WHEN OTHERS THEN
DBMS_OUTPUT.put_line('exception '||SQLERRM || 'message'||sqlcode);
END;

We can create table in procedure as explained in above case. but we can't create or perform any DDL in functions.
