MSSQLSERVER 根据姓名保存姓名的拼音字段
1.申明一个函数，用于名字到拼音的转换
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
2.测试
select dbo.f_GetPY('风云') as 东莞市,dbo.f_GetPY('ab中c国人') as 中国人
3.在数据库中新加一个PinYin字段，然后通过函数进行更新
update person_main_test set PinYin=dbo.f_GetPY(Name)
