SQL汉字转换为拼音的函数

　　本文标签：SQL 函数

　　SQL中有多种的函数，下面为您介绍sql中汉字转换为拼音的函数，供您参考  。数据库中先自定义一个函数，再把下面代码写进去，功能是得到汉字拼音首字母：

　　如下：

　　

view source
print?
01 create function fun_getPY(@str nvarchar(4000))
02 returns nvarchar(4000)
03 as
04 begin
05 declare @word nchar(1),@PY nvarchar(4000)
06 set @PY=
07 while len(@str)>0
08 begin
09 set @word=left(@str,1)
10 --如果非汉字字符，返回原字符
11 set @PY=@PY+(case when unicode(@word) between 19968 and 19968+20901
12 then (select top 1 PY from (
13 select A as PY,N驁 as word
14 union all select B,N簿
15 union all select C,N錯
16 union all select D,N鵽
17 union all select E,N樲
18 union all select F,N鰒
19 union all select G,N腂
20 union all select H,N夻
21 union all select J,N攈
22 union all select K,N穒
23 union all select L,N鱳
24 union all select M,N旀
25 union all select N,N桛
26 union all select O,N漚
27 union all select P,N曝
28 union all select Q,N囕
29 union all select R,N鶸
30 union all select S,N蜶
31 union all select T,N籜
32 union all select W,N鶩
33 union all select X,N鑂
34 union all select Y,N韻
35 union all select Z,N咗
36 ) T 
37 where word>=@word collate Chinese_PRC_CS_AS_KS_WS 
38 order by PY ASC) else @word end)
39 set @str=right(@str,len(@str)-1)
40 end
41 return @PY
42 end

　　

　　--函数调用实例：
select dbo.fun_getPY(中华人民共和国)
结果都为：ZHRMGHG
