Table created.In addition to what others have posted you may also want to research SQL Injection.
For example what do you think will happen if I invoke your procedure as follows:
begin
  stp_temp('bad_table on commit preserve rows as select * from all_users --');
end;
/Is it what you want to have happen?
This is one reason why doing DDL in a stored procedure is a bad idea. Pay particular attention to what SomeoneElse and RP have to say too.
And, for the record, the SQL and PL/SQL forum is PL/SQL.
