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) = 12 THEN 'Twelve'
                        WHEN SUBSTRING(@v, 2, 2) = 13 THEN 'Thirteen'
                        WHEN SUBSTRING(@v, 2, 2) = 14 THEN 'Fourteen'
                        WHEN SUBSTRING(@v, 2, 2) = 15 THEN 'Fifteen'
                        WHEN SUBSTRING(@v, 2, 2) = 16 THEN 'Sixteen'
                        WHEN SUBSTRING(@v, 2, 2) = 17 THEN 'Seventeen'
                        WHEN SUBSTRING(@v, 2, 2) = 18 THEN 'Eighteen'
                        WHEN SUBSTRING(@v, 2, 2) = 19 THEN 'Nineteen'
                        ELSE '' END




            ELSE '' END)
    + ' ' +
    (CASE   WHEN SUBSTRING(@v, 2, 1) = 1 THEN ''
            WHEN SUBSTRING(@v, 3, 1) = 2 THEN 'Two'
            WHEN SUBSTRING(@v, 3, 1) = 3 THEN 'Three'
            WHEN SUBSTRING(@v, 3, 1) = 4 THEN 'Four'
            WHEN SUBSTRING(@v, 3, 1) = 5 THEN 'Five'
            WHEN SUBSTRING(@v, 3, 1) = 6 THEN 'Six'
            WHEN SUBSTRING(@v, 3, 1) = 7 THEN 'Seven'
            WHEN SUBSTRING(@v, 3, 1) = 8 THEN 'Eight'
            WHEN SUBSTRING(@v, 3, 1) = 9 THEN 'Nine'
            WHEN SUBSTRING(@v, 3, 1) = 1 THEN 'One'
            ELSE '' END)
    END
