Establishing Source Code Security With WRAP In Oracle

In Oracle you can wrap your source code, packages, functions e.g., with built-in wrap utility. Securing source code is an important responsibility for enterprise projects. It is possible to compile a wrapped package. It can not possible to see a wrapped source code with selecting all_source view or using dbms_metada built-in package.

Below i demonstrate how can wrap function with wrap utility:


create or replace function get_day( pid_Date in date ) return varchar2 is
begin
  ---For debug, conditional compilation
  $if $$debug = true $then
    dbms_output.put_line( 'INFO@get_day>Date is ' || pid_Date );
  $end
  ---
  return to_char(pid_Date, 'DAY');
end;
/

Call WRAP Utility:
