--对于汉字特殊字符，不生成拼音码
if (
ascii(

>127)
set @temp = ‘‘
--对于英文中小括号，不生成拼音码
if @temp = ‘(‘ or @temp = ‘)‘ set @temp = ‘‘
select @strRet = @temp + @strRet
set @intLen = @intLen - 1
end
return lower(

end
使用
SELECT Product_ID , dbo.fn_GetPy(Product_Name) AS pymc FROM dbo.T_Product
update dbo.T_Product set Product_Pinyin=dbo.fn_GetPy(Product_Name)
