记录一次SQL查询语句

以前发现比较经典的句子，都是记录在电脑上，我今天想搬到博客上，在我看来，写博客真的是一件非常头疼的事，它是内心的一道坎，我必须得跨过它。

 CREATE TABLE t_jeff (
   id int NOT NULL,
   VINNumber varchar(255) DEFAULT NULL,
  ChannelID varchar(255) DEFAULT NULL,
   TimeStamp datetime DEFAULT NULL,
   PRIMARY KEY (id)
 ) ;
 INSERT INTO t_jeff VALUES ('', 'Group3', '', '2015-05-27 00:00:00');
 INSERT INTO t_jeff VALUES ('', 'Group2', '', '2015-05-23 00:00:00');
 INSERT INTO t_jeff VALUES ('', 'Group1', '', '2015-05-25 00:00:00');
 INSERT INTO t_jeff VALUES ('', 'Group2', '', '2015-05-29 00:00:00');
 INSERT INTO t_jeff VALUES ('', 'Group1', '', '2015-05-30 00:00:00');

 SELECT * FROM t_jeff
 --1、VINNumber同组的放一起
 --2、组之间排序逻辑：按照每组ChannelID最大值 倒序
 --3、组内排序：按照ChannelID倒序。

 SELECT  A.*
 FROM    [dbo].[t_jeff] A
         JOIN ( SELECT   MAX([ChannelID]) AS [MaxChannelID] ,
                         [VINNumber]
                FROM     [dbo].[t_jeff]
                GROUP BY [VINNumber]
              ) B ON A.VINNumber = B.VINNumber
 ORDER BY B.MaxChannelID DESC ,
         A.ChannelID DESC
