create function 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 '吖 ', 'A ' union all select '八 ', 'B ' union all 
 select '嚓 ', 'C ' union all select '咑 ', 'D ' union all 
 select '妸 ', 'E ' union all select '发 ', 'F ' union all

 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

SQLSERVER数据库可以这样

追问我的是oracle数据库，left不支持，不知道应该采用那个关键字代替

追答改成 substr(拼音查询,1,1)='A'
