【转】SQL汉字转换为拼音的函数

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
