MSSQL 将人名解析成拼音的SQL函数
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,
hz2 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'
UNION ALL SELECT 'D',N'哒',N'跺'
UNION ALL SELECT 'E',N'屙',N'贰'
UNION ALL SELECT 'F',N'发',N'馥'
UNION ALL SELECT 'G',N'旮',N'过'
UNION ALL SELECT 'H',N'铪',N'蠖'
UNION ALL SELECT 'J',N'丌',N'竣'
UNION ALL SELECT 'K',N'咔',N'廓'
UNION ALL SELECT 'L',N'垃',N'雒'
UNION ALL SELECT 'M',N'妈',N'穆'
UNION ALL SELECT 'N',N'拿',N'糯'
UNION ALL SELECT 'O',N'噢',N'沤'
UNION ALL SELECT 'P',N'趴',N'曝'
UNION ALL SELECT 'Q',N'七',N'群'
UNION ALL SELECT 'R',N'蚺',N'箬'
UNION ALL SELECT 'S',N'仨',N'锁'
UNION ALL SELECT 'T',N'他',N'箨'
UNION ALL SELECT 'W',N'哇',N'鋈'
UNION ALL SELECT 'X',N'夕',N'蕈'
UNION ALL SELECT 'Y',N'丫',N'蕴'
UNION ALL SELECT 'Z',N'匝',N'做'
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
WHERE SUBSTRING(@str,@i,1) BETWEEN hz1 AND hz2
RETURN(@str)
END
GO
--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
