this ms sql function will convert any numeric value to words eg. 65000 to Sixty Five Thousand. I found this code while I writing an Invoice application where I had to display the amount in words.

set @str=@str (select Name From @Decades where Id= (@Amount- @Amount%10)) ' ' (select Name From @Ones where Id=(@Amount%10)) ' '
if(@Amount >= 100 AND @Amount <=999)
set @str=@str dbo.NumberToWords(@Amount/100) ' Hundred ' dbo.NumberToWords(@Amount%100)
