Hello all.
I have a funtion in MYSQL to substruct days from a date.
This function seamsto work but some dates it times out.
This is my function

CREATE DEFINER=`root`@`localhost` FUNCTION `Calculater`(intrval int, req date) RETURNS date
    DETERMINISTIC
BEGIN
declare calculated date;
declare added int default  0;

Lbl_Loop: Loop
IF added=intrval then
leave lbl_loop;
End IF;
set calculated = DATE_SUB(req,interval 1 day);
IF weekday(calculated)<5  then
set added= added+1;
End If;
end loop;
RETURN calculated;
END

If I do select Calculater(1,"2020-02-04"); it works, but select Calculater(1,"2020-02-02"); it runs for a few seconds and My SQL times out.

Thanks in advance.
