1.第一个函数是取得姓名每个中文汉字的第一个字母
CREATE FUNCTION f_GetPY(@str nvarchar(4000))
RETURNS nvarchar(4000)
AS
BEGIN
DECLARE @py TABLE(
ch char(1),
hz1 nchar(1) COLLATE Chinese_PRC_CS_AS_KS_WS,

INSERT @py SELECT 'A',N'吖',N'鏊'
UNION ALL SELECT 'B',N'八',N'簿'
UNION ALL SELECT 'C',N'嚓',N'错'

DECLARE @i int
SET @i=PATINDEX('%[吖-做]%' COLLATE Chinese_PRC_CS_AS_KS_WS,@str)
WHILE @i>0
SELECT @str=REPLACE(@str,SUBSTRING(@str,@i,1),ch)
,@i=PATINDEX('%[吖-做]%' COLLATE Chinese_PRC_CS_AS_KS_WS,@str)
FROM @py

RETURN(@str)

--用法
select dbo.f_GetPY('吴蔚玲') as 东莞市,dbo.f_GetPY('ab中c国人') as 中国人
--将已有表中的某个字段更新成拼音字段
select name,pinyin from person_main_test
update person_main_test set PinYin=dbo.f_GetPY(Name)
2.获得整个中文名字的拼音
create function f_getpyALL(@str varchar(100))
returns varchar(8000)
as
begin
declare @returnValue varchar(8000)
declare @re table(id int,re varchar(8000))
declare @i int,@ilen int,@splitchr varchar(1)
select @splitchr='' ,@i=1,@ilen=len(@str)
insert into @re select @i,py from YingShe where chr=substring(@str,@i,1)
while @i<@ilen
begin
set @i=@i+1
insert into @re select @i,re+@splitchr+py from @re a,YingShe b
where a.id=@i-1 and b.chr=substring(@str,@i,1)
end
select @returnValue= re from @re where id=@i
return (@returnValue)
end
