我正在试图弄清楚如何编写我的SQL查询以获得用户的日常和保留。 考虑使用以下行表round_statistics 在每轮比赛中,我有一轮的日期, 现在我想: 1.知道有多少用户连续两天玩,意思是在周日和周一,周一和周二播放,但周日和周二不算连续两天。 2.用户保留1-7
保留7是:有机会玩最近7天的用户的百分比(意味着他们至少注册了7天)并且在7天后有一些活动(记录)。
保留6-1仅在6-1天内相同。
请帮我查一下我的游戏保留情况:)你会得到一个免费的硬币玩它.... 感谢。
表结构是: USER_ID,round_time
例如,如果我今天玩了3次:
user id | round_time
1000, | '2013-08-10 14:02:53'
1000, | '2013-08-10 14:03:25'
1000, | '2013-08-10 14:04:47'
结果结构是:
date | 2013-08-10 | 2013-07-10
day to day | 10 | 100
retention 7 | 15 | 125
retention 6 | 20 | 210
retention 5 | 30 | 320
retention 4 | 40 | 430
retention 3 | 50 | 540
retention 2 | 60 | 650
retention 1 | 120 | 1620
答案 0 :(得分:2)
我的sql没有analytic functions,CTE和数据透视表功能都没有,因此不能直接执行您所需的查询(没有人回答您的问题)。
对于这些数据:
create table t ( uid int, rt date);
insert into t values
(99, '2013-08-7 14:02:53' ), <- gap
(99, '2013-08-9 14:02:53' ), <-
(99, '2013-08-10 14:03:25' ),
(1000, '2013-08-7 14:02:53' ),
(1000, '2013-08-8 14:03:25' ),
(1000, '2013-08-9 14:03:25' ),
(1000, '2013-08-10 14:04:47');
对于给定日期( '2013-08-10 00:00:00' , '%Y-%m-%d')
:
select count( distinct uid ) as n, d, dt from
(
select uid,
'2013-08-10 00:00:00' as d,
G.dt
from
t
inner join
( select 7 as dt union all
select 6 union all select 5 union all
select 4 union all select 3 union all
select 2 union all select 1 union all select 0) G
on DATE_FORMAT( t.rt, '%Y-%m-%d') between
DATE_FORMAT( date_add( '2013-08-10 00:00:00', Interval -1 * G.dt DAY) ,
'%Y-%m-%d')
and
DATE_FORMAT( '2013-08-10 00:00:00' , '%Y-%m-%d')
where DATE_FORMAT(rt , '%Y-%m-%d') <= DATE_FORMAT( '2013-08-10 00:00:00' ,
'%Y-%m-%d')
group by uid, G.dt
having count( distinct DATE_FORMAT( T.rt, '%Y-%m-%d') ) = G.dt + 1
) TT
group by dt
您的预煮数据(DT = 0表示今天访问,DT = 1表示连续2天,......):
| N | D | DT |
--------------------------------
| 2 | 2013-08-10 00:00:00 | 0 |
| 2 | 2013-08-10 00:00:00 | 1 |
| 1 | 2013-08-10 00:00:00 | 2 |
| 1 | 2013-08-10 00:00:00 | 3 |
这是(对于相同的数据):
select count( distinct uid ) as n, d, dt from
(
select uid,
z.zt as d,
G.dt
from
t
cross join
( select distinct DATE_FORMAT( t.rt, '%Y-%m-%d') as zt from t) z
inner join
( select 7 as dt union all
select 6 union all select 5 union all
select 4 union all select 3 union all
select 2 union all select 1 union all select 0) G
on DATE_FORMAT( t.rt, '%Y-%m-%d') between
DATE_FORMAT( date_add( z.zt, Interval -1 * G.dt DAY) ,
'%Y-%m-%d')
and
z.zt
where z.zt <= z.zt
group by uid, G.dt, z.zt
having count( distinct DATE_FORMAT( T.rt, '%Y-%m-%d') ) = G.dt + 1
) TT
group by d,dt
order by d,dt
在sqlfiddle的结果:http://sqlfiddle.com/#!2/c26ec/10/0
| N | D | DT | GROUP_CONCAT( UID) |
--------------------------------------------
| 2 | 2013-08-07 | 0 | 1000,99 |
| 1 | 2013-08-08 | 0 | 1000 |
| 1 | 2013-08-08 | 1 | 1000 |
| 2 | 2013-08-09 | 0 | 1000,99 |
| 1 | 2013-08-09 | 1 | 1000 |
| 1 | 2013-08-09 | 2 | 1000 |
| 2 | 2013-08-10 | 0 | 1000,99 |
| 2 | 2013-08-10 | 1 | 99,1000 |
| 1 | 2013-08-10 | 2 | 1000 |
