怎样写SQL函数汉字转换拼音简码
我想定义一个函数对字段中汉字更新为拼音简码（多个汉字），但是下面这段函数只能对第一个汉字转换。有哪位高手帮帮忙写一个能转换多个汉字的函数，修改下面的函数也可。
create function f_ch2py(@chn nchar(1)) /*nchar固定长度的 Unicode 数据*/
returns char(1)
as
begin
declare @n int
declare @c char(1)
set @n = 63
select @n = @n +1,
@c = case chn when @chn then char(@n) else @c end
from(
select top 27 * from (
select chn =
'吖' union all select
'八' union all select
'嚓' union all select
'咑' union all select
'妸' union all select
'发' union all select
'旮' union all select
'铪' union all select
'丌' union all select --because have no 'i'
'丌' union all select
'咔' union all select
'垃' union all select
'呒' union all select
'拏' union all select
'噢' union all select
'妑' union all select
'七' union all select
'呥' union all select
'仨' union all select
'他' union all select
'屲' union all select --no 'u'
'屲' union all select --no 'v'
'屲' union all select
'夕' union all select
'丫' union all select
'帀' union all select @chn) as a
order by chn COLLATE Chinese_PRC_CI_AS
) as b
return(@c)
end
go
