Answer 1

Did you need PIPELINED Function?

Or RECORD ???
DECLARE
  TYPE EmpRec IS RECORD(
    v_first employees.fn%TYPE,
    v_second  employees.sl%TYPE,
    v_third    employees.hd%TYPE);
  r_emprec EmpRec;
BEGIN
  SELECT first_name, salary, hire_date
    INTO r_emprec
    FROM employees
   WHERE employee_id = 100;
  DBMS_OUTPUT.PUT_LINE('Employee #' || r_emprec.v_first || ' = ' ||
                       r_emprec.v_second || ' ' || r_emprec.v_third);
END;
which one?
