SQL中定義函式，將漢字轉成拼音簡寫

我們在寫程式中，經常會用到sql中將某個名字轉成拼音，然後儲存在資料庫中某個欄位中，方便快捷查詢，所以有必要寫sql函式來定義一下，話補多說，直接上**：

create  function  fn_getpy(@str  nvarchar(4000

)) 
returns nvarchar(
4000
) --用於加密
--with encryption 
asbegin 
declare @intlen 
intdeclare @strret nvarchar(
4000
) declare @temp nvarchar(
100) 
set @intlen =len(@str) 
set @strret = ''
while @intlen > 0
begin 
set @temp = ''
select @temp = case
when substring(@str,@intlen,
1) >= '
帀' then 'z'
when substring(@str,@intlen,
1) >= '
丫' then 'y'
when substring(@str,@intlen,
1) >= '
夕' then 'x'
when substring(@str,@intlen,
1) >= '
屲' then 'w'
when substring(@str,@intlen,
1) >= '
他' then 't'
when substring(@str,@intlen,
1) >= '
仨' then 's'
when substring(@str,@intlen,
1) >= '
呥' then 'r'
when substring(@str,@intlen,
1) >= '
七' then 'q'
when substring(@str,@intlen,
1) >= '
妑' then 'p'
when substring(@str,@intlen,
1) >= '
噢' then 'o'
when substring(@str,@intlen,
1) >= '
拏' then 'n'
when substring(@str,@intlen,
1) >= '
嘸' then 'm'
when substring(@str,@intlen,
1) >= '
垃' then 'l'
when substring(@str,@intlen,
1) >= '
咔' then 'k'
when substring(@str,@intlen,
1) >= '
丌' then 'j'
when substring(@str,@intlen,
1) >= '
鉿' then 'h'
when substring(@str,@intlen,
1) >= '
旮' then 'g'
when substring(@str,@intlen,
1) >= '
發' then 'f'
when substring(@str,@intlen,
1) >= '
妸' then 'e'
when substring(@str,@intlen,
1) >= '
咑' then 'd'
when substring(@str,@intlen,
1) >= '
嚓' then 'c'
when substring(@str,@intlen,
1) >= '
八' then 'b'
when substring(@str,@intlen,
1) >= '
吖' then 'a'
else rtrim(ltrim(substring(@str,@intlen,1
))) 
end 
--對於漢字特殊字元，不生成拼音碼 
if (ascii(@temp)>127) set @temp = '' 
--對於英文中小括號，不生成拼音碼 
if @temp = '
(' or @temp = ')'
set @temp = ''
select @strret = @temp +@strret 
set @intlen = @intlen - 1
end 
return
lower(@strret) 
end

呼叫方式：

select dbo.fn_getpy('

張三丰') py

結果如下：

pyzsf
