Question

我需要根据组找到系统中活动用户的运行总数如果用户当前处于暂停状态，则不应在当前计数中考虑该用户，而应在其活跃时考虑该用户对于前用户在2019年4月被停职，因此在进行所有计数之前，应该将他视为活跃用户

“用户”表包含状态（“活动” /“已暂停”）和“更新”列我已经编写了代码，但是由于仅考虑当前的活动用户，因此并没有达到预期效果

 SELECT DISTINCT Concat(year(b1.created_at),'-',monthname(b1.created_at)) Date,c1.name as 'GroupName',
(   
    select 
    count(distinct(b.user_id))      from 
        users u2 join teams_users b on u2.id = b.user_id join teams c on b.team_id = c.id  
    where 
    year(b.created_at)*100 + month(b.created_at) <= year(b1.created_at)*100+month(b1.created_at)
     and 
    u2.organization_id =1690 
             and u2.status = 'Active' 
    and c.organization_id = 1690 
     and c.id =c1.id
    ) total_users
 from users u1 join teams_users b1 on u1.id = b1.user_id 
 join teams c1 on b1.team_id = c1.id
 where 
     u1.organization_id =1690  and u1.status = 'Active'

用户

 UserId|CreatedOn|Status|Updatedon

团队

 Id|Name

Team_users

 Team_id|User_id|CreatedOn

Here's a sample query that will get you a total number of users in a given month, per month, per team:

with generator as
(
SELECT 0 n UNION ALL SELECT 1  UNION ALL SELECT 2  UNION ALL 
   SELECT 3   UNION ALL SELECT 4  UNION ALL SELECT 5  UNION ALL
   SELECT 6   UNION ALL SELECT 7  UNION ALL SELECT 8  UNION ALL
   SELECT 9   UNION ALL SELECT 10 UNION ALL SELECT 11 UNION ALL
   SELECT 12  
),
user_to_team as
(
   select user_id
        , team_id
        , tu.created_at as date_joined
        , case 
            when u.status = 'suspended'
            then u.updatedon
            else curdate()
          end member_until
     from team_users tu
     join users u
       on u.id = tu.user_id
), periods as
(
   select year*100 + month as period
     from (select 2018+n as year from generator where n < 2) x
    cross
     join (select 1+n as month from generator where n<12) y
)
select periods.period
     , t.id
     , count(u2t.user_id)
  from periods
  join teams t
    on year(t.created_at) * 100 + month(t.created_at) <= periods.period
  left outer
  join user_to_team u2t
    on periods.period between year(u2t.date_joined)*100 + month(u2t.date_joined) and year(u2t.member_until)*100 + month(u2t.member_until)
   and u2t.team_id = t.id
 where periods.period <= year(curdate())*100 + month(curdate())
group by periods.period, t.id
order by periods.period, t.id

generator CTE is for generating numbers, we'll need that in periods to generate a list of year-months (yyyymm). If you have a numbers table, you can use that. user_to_team CTE just lists the relations between users with when they joined (record in user_teams created) and until when they were members (either updatedon of the user if they are suspended, or current date). Then it's just a matter of joining our periods to teams and the user_to_team to that based on dates - teams are joined ever since they were created and members to period between which they existed.

Here's a working sample on dbfiddle

There are two teams:

team 1 created in 2019-01
team 2 created in 2019-02

Users:

user 1, active
user 2, suspended since 2019-03

Team to User:

user 1 in team 1 since 2019-01, in team 2 since 2019-03
user 2 in team 1 since 2019-03, in team 2 since 2019-03

按组计算活动用户的运行总数
