Answer 1

I Just Updated a function in MySql from 999 up to 999999999 number

this is the link to the original one:Reference

And the Updated one is bellow:

---

CREATE FUNCTION `number_to_string`(n INT) RETURNS varchar(1000) CHARSET latin1 BEGIN
    declare ans varchar(1000);
    declare dig1, dig2, dig3,dig4,dig5,dig6,dig7,dig8,dig9 int;

    set ans = '';
    set dig9 = floor(n/100000000);
    set dig8 = floor(n/10000000) - dig9*10;
    set dig7 = floor(n/1000000) -(floor(n/10000000)*10);
    set dig6 = floor(n/100000) - (floor(n/1000000)*10);
    set dig5 = floor(n/10000) -  (floor(n/100000)*10);
    set dig4 = floor(n/1000) -   (floor(n/10000)*10);
    set dig3 = floor(n/100) -    (floor(n/1000)*10);
    set dig2 = floor(n/10) -     (floor(n/100)*10);
    set dig1 = n - (floor(n / 10)*10);

If dig9 > 0 then

        case

I tested it like that: select number_to_string(999999999)

and results: 'Nine Hundred And Ninety Nine Million And Nine Hundred And Ninety Nine Thousand And Nine Hundred And Ninety Nine'
