SQL中文转拼音

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'

WHERE word>=@word COLLATE Chinese_PRC_CS_AS_KS_WS

SET @str=RIGHT(@str,LEN(@str)-1)
