create table tabpy(id int identity,b_begin varbinary(2),b_end varbinary(2),word varchar(2))

函数：
create function getfirstpy(@a varchar(200))
returns varchar(100)
as
begin
declare @i int,@j int,@result varchar(100)
set @result=''
set @i=len(@a)
set @j=1
while @j<=@i
begin
select @result=@result+word from tabpy where cast(substring(@a,@j,1) as varbinary(2)) between b_begin and b_end
set @j=@j+1
end
return @result
end追答只能用数据库的形式，如果你对GB2312编码有研究的话，你会知道，它的码表是按换汉语拼音来排的，这样你做数据库的时候可以参考GB2312的标准，可以把数据库设计得稍微简单那么一点点。
