如何在SQL Server 2008中使用base32编码int

CREATE FUNCTION dbo.Base10toBase32 (@pInput int)
RETURNS varchar(100)
AS
BEGIN
    Declare @pSet char(32)
    Declare @pRslt varchar(100)
    Declare @pRmdr int
    Declare @pPos int

    SET @pSet = \'0123456789ABCDEFGHIJKLMNOPQRSTUV\'
    SET @pPos = @pInput

    WHILE @pPos > 0
    BEGIN
        SET @pRmdr = @pPos % 32
        SET @pPos = @pPos / 32
        SET @pRslt = SubString(@pSet,@pRmdr+1,1) + @pRslt
    END

    RETURN @pRslt
END
