SQL切分字符串成int和for xml path

切分字符

SqlServer切割字符串示例：

--declare    @StrDId nvarchar(2000)
--set @StrDId='100,200,400,500,600'

--转换ID，防止注入

CREATE TABLE #table_DId( ID INT)
While(CHARINDEX(',',@StrDId)<>0)
Begin
    Insert Into #table_DId(ID) Values(CONVERT(Int,Substring(@StrDId,1,CHARINDEX(',',@StrDId)-1)));
    Set @StrDId=STUFF(@StrDId,1,CHARINDEX(',',@StrDId),'');
End
Insert Into #table_DId (ID) Values(CONVERT(Int,@StrDId));

/// <summary>
        /// 获取IP地址
        /// </summary>
        public static string GetIPAddress()
        {
            string _result = string.Empty;
            _result = HttpContext.Current.Request.ServerVariables["HTTP_CDN_SRC_IP"];
            if (string.IsNullOrEmpty(_result))
                _result = HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"];
            if (string.IsNullOrEmpty(_result))
                _result = HttpContext.Current.Request.UserHostAddress;
            if (string.IsNullOrEmpty(_result) || !IsIP(_result))
                return "127.0.0.1";
            return _result;
        }
        /// <summary>
        /// 正则判断
        /// </summary>
        private static bool IsIP(string ip)
        {
            return Regex.IsMatch(ip, "^((2[0-4]\\d|25[0-5]|[01]?\\d\\d?)\\.){3}(2[0-4]\\d|25[0-5]|[01]?\\d\\d?)$");
        }

begin try
begin transaction 

commit transaction
end try
begin catch
select ERROR_NUMBER() as errornumber,ERROR_LINE() as errorline,ERROR_MESSAGE() as errormessage
rollback transaction
end catch

for xml path

--每行数据根节点row,数据列名子节点
select * from Table for xml path

--path('参数')指定名称替换row;列名可以用as 替换
select Name as 'S-Name' from Table for xml path('')

--单列纯文本:根节点用path('') +列名不命名；输出纯文本
select Name+''  from Table for xml path('')
