采用mysql 5.6

业务需求：

1、管理员上传视频，然后用户进行视频观看，统计用户点击视频的次数，进行日排行排序

表设计:

CREATE TABLE `v_video_play_log` (
  `id` bigint(20) NOT NULL DEFAULT '0' COMMENT 'id',
  `VideoId` bigint(20) DEFAULT NULL COMMENT '视频id',
  `memberId` bigint(20) DEFAULT NULL COMMENT '会员id',
  `ip` varchar(128) DEFAULT NULL COMMENT '观看人ip',
  `lookTime` datetime DEFAULT NULL COMMENT '点击观看时间',
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COMMENT='视频点播记录表';


插入模拟数据：

sql实现：

-- 总查询括号出来，方便order by 排序
SELECT *
	FROM (
	SELECT 
   -- 通过case方法判断，变量日期@pre_lookTime，是否等于上一个日期，一样的话，则数字序号加1，不一样，则需要从1开始
		@i := 
		CASE 
			WHEN 
				@pre_lookTime = a.lookTime 
				THEN 
					-- 通过case嵌套方法判断，变量点击数@pre_num，是否等于上一个点击数，一样的话，则并列排名，不一样，则数字序号加1
						CASE 
							WHEN @pre_num = a.clickNum 
							THEN @i 
							ELSE @i + 1 
							END 
				ELSE 1 
				END AS rownum, 
	    -- 将变量@pre_lookTime 等于上一条数据日期（即，根据sql查询的顺序赋值，变量等于当条数据的值，在下一条数据时，就等于上条数据的值）
				@pre_lookTime := a.lookTime AS prelookTime,
			-- 将变量@pre_lookTime 等于上一条数据号码
				@pre_num := a.clickNum AS preclickNum,
				a.*
				FROM (
			-- 将时间转换成yyyymmdd格式，进行分组排序，按日期排序
				SELECT COUNT(lo.id) AS clickNum, lo.id, lo.VideoId, lo.memberId, lo.ip
				, looklo.lookTime
				FROM v_video_play_log lo, (SELECT DATE_FORMAT(lookTime, '%Y%m%d') AS lookTime, id
				FROM v_video_play_log
				) looklo
		WHERE lo.id = looklo.id
		GROUP BY looklo.lookTime, VideoId
		ORDER BY looklo.lookTime DESC, COUNT(lo.id) DESC
		) a,
	-- 查询一个变量@i,赋值0，变量@pre_lookTime，赋值null，变量 @pre_num ，赋值0
	(SELECT @i := 0, @pre_lookTime := NULL, @pre_num := 0
		) b
	) c
ORDER BY looktime DESC;
