How to determine a PL/SQL function's schema from within the function

Question

I have a PL/SQL package in an Oracle 10g database and I want to write a function that returns the name of the schema that the package (and hence the function) is defined in. Anyone know how to do this?

Answer 1

create function xcurr return varchar2 is
  v_curr varchar2(32);
begin
  SELECT SYS_CONTEXT ('USERENV', 'CURRENT_USER') into v_curr from dual;
  return v_curr;
end;

This will work as long as the PL/SQL object doesn't have AUTHID CURRENT_USER.
