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

 还有for json path转换json

--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('')

 

每隔2个字符插入冒号

select t.*,

       rtrim(substr(value, 1, 2) ||bai ':' || substr(value, 3, 2) || ':' ||

             substr(value, 5, 2) || ':' || substr(value, 7, 2),

             ':') value2

  from test_split t;

 

组内排序

select AN, BN,10+ROW_NUMBER() OVER (PARTITION BY 分组列  ORDER BY 排序列) AS NUM from #temp
