This seems like a simpler approach, a nice recursive algorithm

CREATE FUNCTION fnIntegerToWords(@Number as BIGINT) 
    RETURNS VARCHAR(1024)
AS

BEGIN
      DECLARE @Below20 TABLE (ID int identity(0,1), Word varchar(32))
      DECLARE @Below100 TABLE (ID int identity(2,1), Word varchar(32))
      INSERT @Below20 (Word) VALUES 
                        ( 'Zero'), ('One'),( 'Two' ), ( 'Three'),
                        ( 'Four' ), ( 'Five' ), ( 'Six' ), ( 'Seven' ),
                        ( 'Eight'), ( 'Nine'), ( 'Ten'), ( 'Eleven' ),
                        ( 'Twelve' ), ( 'Thirteen' ), ( 'Fourteen'),
                        ( 'Fifteen' ), ('Sixteen' ), ( 'Seventeen'),
                        ('Eighteen' ), ( 'Nineteen' ) 

       INSERT @Below100 VALUES ('Twenty'), ('Thirty'),('Forty'), ('Fifty'),
                               ('Sixty'), ('Seventy'), ('Eighty'), ('Ninety')

    declare @belowHundred as varchar(126) 

    if @Number > 99 begin
        select @belowHundred = dbo.fnIntegerToWords( @Number % 100)
    end

    DECLARE @English varchar(1024) = 

    (

      SELECT Case 
        WHEN @Number = 0 THEN  ''

        WHEN @Number BETWEEN 1 AND 19 
          THEN (SELECT Word FROM @Below20 WHERE ID=@Number)

       WHEN @Number BETWEEN 20 AND 99   
         THEN  (SELECT Word FROM @Below100 WHERE ID=@Number/10)+ '-' +
               dbo.fnIntegerToWords( @Number % 10) 

       WHEN @Number BETWEEN 100 AND 999   
         THEN  (dbo.fnIntegerToWords( @Number / 100)) +' Hundred '+
             Case WHEN @belowHundred <> '' THEN 'and ' + @belowHundred else @belowHundred end 

       WHEN @Number BETWEEN 1000 AND 999999   
         THEN  (dbo.fnIntegerToWords( @Number / 1000))+' Thousand '+
             dbo.fnIntegerToWords( @Number % 1000)  

       WHEN @Number BETWEEN 1000000 AND 999999999   
         THEN  (dbo.fnIntegerToWords( @Number / 1000000))+' Million '+
             dbo.fnIntegerToWords( @Number % 1000000) 

       WHEN @Number BETWEEN 1000000000 AND 999999999999   
         THEN  (dbo.fnIntegerToWords( @Number / 1000000000))+' Billion '+
             dbo.fnIntegerToWords( @Number % 1000000000) 

            ELSE ' INVALID INPUT' END
    )

    SELECT @English = RTRIM(@English)

    SELECT @English = RTRIM(LEFT(@English,len(@English)-1))
        WHERE RIGHT(@English,1)='-'

    RETURN (@English)

END

Also, you can CREATE TABLE with numbers and their names.

CREATE TABLE tblNumbers (Nmb int, NmbWord varchar(100))
INSERT INTO tblNumbers 
VALUES (1,'first'), (2,'second'),(3,'third'), (4,'forth')

CREATE TABLE SomeTable (nmb int)

INSERT INTO SomeTable 
VALUES (1), (1),(2),(3)

SELECT  N.*
FROM tblNumbers N
     JOIN SomeTable ST ON ST.nmb=N.Nmb

DROP TABLE tblNumbers
DROP TABLE SomeTable

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
            when dig9=1 then set ans=concat(ans, 'One Hundred');
            when dig9=2 then set ans=concat(ans, 'Two Hundred');

                when dig1=9 then set ans=concat(ans, ' Nine');
                else set ans=ans;
            end case;
        end if;
    end if;

    return trim(ans);
    END

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'

You need to use a CASE statement:

SELECT intfield CASE WHEN 1 THEN 'First'
                     WHEN 2 THEN 'Second'
                     WHEN 3 THEN 'Third'
                     ...other conversions...
                     ELSE '' END
FROM Mytable

EDIT:

Working code for 3 character numbers below. You can add the needed code below it for 2 and 1 character numbers (basically just modify what I wrote and change the SUBSTRINGs accordingly).

Essentially it converts the number to a string, checks how many numbers there are, then breaks it down accordingly.

DECLARE @n int = 515

DECLARE @v varchar(100) = CAST(@N as varchar)

SELECT CASE WHEN LEN(@v) = 3 THEN 
    (CASE   WHEN LEFT(@v, 1) = 1 THEN 'One Hundred'
            WHEN LEFT(@v, 1) = 2 THEN 'Two Hundred'
            WHEN LEFT(@v, 1) = 3 THEN 'Three Hundred'
            WHEN LEFT(@v, 1) = 4 THEN 'Four Hundred'
            WHEN LEFT(@v, 1) = 5 THEN 'Five Hundred'
            WHEN LEFT(@v, 1) = 6 THEN 'Six Hundred'
            WHEN LEFT(@v, 1) = 7 THEN 'Seven Hundred'
            WHEN LEFT(@v, 1) = 8 THEN 'Eight Hundred'
            WHEN LEFT(@v, 1) = 9 THEN 'Nine Hundred'
            ELSE '' END)
    + ' ' +
    (CASE   WHEN SUBSTRING(@v, 2, 1) = 2 THEN 'Twenty'
            WHEN SUBSTRING(@v, 2, 1) = 3 THEN 'Thirty'
            WHEN SUBSTRING(@v, 2, 1) = 4 THEN 'Forty'
            WHEN SUBSTRING(@v, 2, 1) = 5 THEN 'Fifty'
            WHEN SUBSTRING(@v, 2, 1) = 6 THEN 'Sixty'
            WHEN SUBSTRING(@v, 2, 1) = 7 THEN 'Seventy'
            WHEN SUBSTRING(@v, 2, 1) = 8 THEN 'Eighty'
            WHEN SUBSTRING(@v, 2, 1) = 9 THEN 'Ninety'
            WHEN SUBSTRING(@v, 2, 1) = 1 THEN 
                CASE    WHEN SUBSTRING(@v, 2, 2) = 10 THEN 'Ten'
                        WHEN SUBSTRING(@v, 2, 2) = 11 THEN 'Eleven'

                        WHEN SUBSTRING(@v, 2, 2) = 16 THEN 'Sixteen'
                        WHEN SUBSTRING(@v, 2, 2) = 17 THEN 'Seventeen'

                        ELSE '' END




            ELSE '' END)
