Sie können Ihre eigene Funktion einfach so in MySQL schreiben:
drop function if exists my_sec_to_time;
delimiter $$
create function my_sec_to_time(p_sec int)
returns varchar(10)
deterministic
begin
declare v_hour int;
declare v_minute int;
declare v_tmp_sec int;
set v_hour = floor(p_sec / 3600);
set v_tmp_sec = p_sec - (v_hour * 3600);
set v_minute = floor(v_tmp_sec / 60);
set v_tmp_sec = v_tmp_sec - (v_minute * 60);
return concat(v_hour, ':', v_minute, ':', v_tmp_sec);
end $$
delimiter ;
In Aktion:
mysql;[email protected](playground)> select my_sec_to_time(3020399);

| my_sec_to_time(3020399) |
