使用下方的函数..

忘了从哪抄的了..留存一份

如果只要首字母..建议将数据  Left(tableFiled,1) 后传入函数

如果字段是空或者null, 不会报错..返回空

方法体: 

SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE FUNCTION [dbo].[F_SYS_getPY]
(
@str NVARCHAR(4000)
)
RETURNS NVARCHAR(4000)
AS
BEGIN
DECLARE @word NCHAR(1),@PY NVARCHAR(4000)
SET @PY=‘‘
WHILE LEN(@str)>0
BEGIN
SET @word=LEFT(@str,1)
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 ‘W‘,N‘鶩‘
UNION ALL SELECT ‘X‘,N‘鑂‘
UNION ALL SELECT ‘Y‘,N‘韻‘
UNION ALL SELECT ‘Z‘,N‘咗‘
) 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
