SQL Server 中将中文转为拼音首字母的函数及调用方法

原文地址：

1、创建函数

Create FUNCTION dbo.fnpbGetPYFirstLetter 
( 
@str NVARCHAR(4000) 
) 
/*
select dbo. fnpbGetPYFirstLetter ('中國香港')
*/
RETURNS NVARCHAR(4000) 
--WITH ENCRYPTION 
AS 
BEGIN 
DECLARE @WORD NCHAR(1),@PY NVARCHAR(4000) SET @PY='' WHILE LEN(@STR)>0 
BEGIN 
SET @WORD=LEFT(@STR,1) --如果非漢字字符﹐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'做' 
) 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 @PY ENDGo

2、函数的调用

select dbo.fnpbGetPYFirstLetter(name), name from tablename
