Konvertera minuter till HH24:MI-format

Om du antar att du vill konvertera 492 minuter:

select to_char(trunc(sysdate) + 492/24/60, 'hh24:mi') from dual;

Om du vill ha en funktion:

create or replace 
  function tq84_convert_minutes_hh24mm (p_minutes in number) 
  return varchar2 is
begin

    return to_char (trunc(sysdate) + p_minutes / 24/60, 'hh24:mi');

end tq84_convert_minutes_hh24mm;
/

Senare ...

begin
  dbms_output.put_line (tq84_convert_minutes_hh24mm(492));
end;
