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：
