感兴趣的小伙伴，下面一起跟随编程之家 52php.cn的小编两巴掌来看看吧！ 代码如下：
代码如下:
USE [tempdb]
GO
/****** Object: UserDefinedFunction [dbo].[fun_getPY] Script Date: 05/23/2012 18:03:45 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
/*
获取汉字的首拼音
如果是非汉字字符
*/
ALTER 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 upper(@PY)
end
调用如下：
代码如下:
select dbo.[fun_getPY]('中国人') 首拼
结果：
