sqlserver 自定义函数汉字转拼音或首字母

作用：

        将汉字生成为全拼音或者首字母，示例

• 执行自定义函数，将汉字转成对应的首字母

• 执行自定义函数，将汉字转成全拼音

自定义教程：

        一，只取汉字的首字母 代码如下：

                执行下面sql 就自定义函数了

SET  ANSI_NULLS ON
SET  QUOTED_IDENTIFIER ON
go

CREATE   FUNCTION  [dbo].[fun_getPY](@str nvarchar(4000) ) 
RETURNS  nvarchar(4000) 
AS  
BEGIN  
  DECLARE @word nchar(1),@PY nvarchar(4000) 
  set @PY='' 
  WHILE len(@str)>0 
  BEGIN    
    set @word=left(@str,1) 

    --如果非汉字字符，返回原字符 
    set @PY=@PY+(case when unicode(@word) between 19968 and 19968+20901 
               then (  
                            select top 1 PY  
                            from  
                            (  
                             select 'A' as PY,N'驁' as word 
                             union all select 'B',N'簿' 
                             union all select 'C',N'錯' 
                     union all select 'D',N'鵽' 
                     union all select 'E',N'樲' 
                     union all select 'F',N'鰒' 
                     union all select 'G',N'腂' 
                     union all select 'H',N'夻' 
                     union all select 'J',N'攈' 
                     union all select 'K',N'穒' 
                     union all select 'L',N'鱳' 
                     union all select 'M',N'旀' 
                     union all select 'N',N'桛' 
                     union all select 'O',N'漚' 
                     union all select 'P',N'曝' 
                     union all select 'Q',N'囕' 
                     union all select 'R',N'鶸' 
                     union all select 'S',N'蜶' 
                     union all select 'T',N'籜' 
                     union all select 'W',N'鶩' 
                     union all select 'X',N'鑂' 
                     union all select 'Y',N'韻' 
                     union all select 'Z',N'咗' 
                      ) T  
                   where word>=@word collate Chinese_PRC_CS_AS_KS_WS  
                   order by PY ASC 
                          )  
                      else @word  
                 end) 
    SET  @str=right(@str,len(@str)-1) 
    END 
    RETURN @PY
END 

GO

SELECT dbo.fun_getPY('来1吧')

执行完上面sql,执行下面：

SELECT dbo.fun_getPY('来1吧')

-- 得到：L1B

二，另一种是取汉字胡全拼 代码如下：

CREATE function [dbo].[fn_GetPinyin](@words nVARCHAR(2000))   
RETURNS VARCHAR(8000)   
AS   

BEGIN 
    DECLARE @word nchar(1) 
    DECLARE @pinyin VARCHAR(8000) 
    DECLARE @i INT
    DECLARE @words_len INT
    DECLARE @unicode INT
    SET @i = 1 
    SET @words =ltrim(rtrim(@words)) 
    SET @words_len =len(@words) 
    WHILE(@i <= @words_len)--循环取字符
    BEGIN 
    SET @word =substring(@words, @i, 1) 
    SET @unicode =unicode(@word) 
    SET @pinyin =ISNULL(@pinyin +SPACE(1),'')+ (CASE WHEN unicode(@word)between 19968 and 19968+20901 then  
    (SELECT TOP  1 py FROM (
