    1:创建函数

    create function   [dbo].[f_GetPy](@str   nvarchar(4000)) 
    returns   nvarchar(4000) 
    as 
    begin 
    declare   @strlen   int,@re   nvarchar(4000) 
    declare   @t   table(chr   nchar(1)   collate   Chinese_PRC_CI_AS,letter   nchar(1)) 
    insert   into   @t(chr,letter) 
        select   '', 'A '   union   all   select   '', 'B '   union   all 
        select   '', 'C '   union   all   select   '', 'D '   union   all 
        select   '', 'E '   union   all   select   '', 'F '   union   all 
        select   '', 'G '   union   all   select   '', 'H '   union   all 
        select   '', 'J '   union   all   select   '', 'K '   union   all 
        select   '', 'L '   union   all   select   '', 'M '   union   all 
        select   '', 'N '   union   all   select   '', 'O '   union   all 
        select   '', 'P '   union   all   select   '', 'Q '   union   all 
        select   '', 'R '   union   all   select   '', 'S '   union   all 
        select   '', 'T '   union   all   select   '', 'W '   union   all 
        select   '', 'X '   union   all   select   '', 'Y '   union   all 
        select   '', 'Z ' 
        select   @strlen=len(@str),@re= ' ' 
        while   @strlen> 0 
        begin 
            select   top   1   @re=letter+@re,@strlen=@strlen-1 
                from   @t   a   where   chr <=substring(@str,@strlen,1) 
                order   by   chr   desc 
            if   @@rowcount=0 
                select   @re=substring(@str,@strlen,1)+@re,@strlen=@strlen-1 
        end 
        return(@re) 
    end
