如果是sql 里面处理的话可以这样设置 写过程 保存 我这个是ms数据库写法
ALTER FUNCTION dbo.procGetPY
(
@str NVARCHAR(4000)
)
/*
select dbo. procGetPYFirstLetter ('中國')
*/
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
END
然后引用 比如你的表里面的姓名是 字段是name
那么就用
select left(dbo.procGetPY (name),1) from tab(你的表)
