按拼音排序与根据英文首字母来查询汉字

时间：2023-01-28 07:56:11

--1. 按拼音排序
DECLARE @t TABLE(col varchar(2))
INSERT @t SELECT '中'
UNION ALL SELECT '国'
UNION ALL SELECT '人'

SELECT * FROM @t ORDER BY col COLLATE Chinese_PRC_CS_AS_KS_WS
/*--结果
col 
----
国
人
中
--*/
GO


/*==========================================*/


--2. 汉字首字母查询处理用户定义函数
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
表结构扩展一个字段用来保存pactname的拼音编码
查询时对应拼音编码查询

  --删除拼音函数  
  drop   function   fgetpy
