Posted 2021-02-02 雁书几封

1、时间字段是datetime类型

2、需要用到中间表，表结构和数据链接下载

3、前两个 adddate 日需要在代码中写死 从每日的-01开始，-最后一个日期同理xxxx-xx-31

4、sql

select
    bri.orgid,
    years.date,
    date_format(years.date, \'%Y-%m\') AS years,
    bri.entrytime a,
    sum( case when bri.status = \'1\' then 1 else 0 end ) as num,
    sum( case when bri.status = \'1\' and bri.sex=\'1\' then 1 else 0 end  ) as numman,
    sum( case when bri.status = \'1\' and bri.sex=\'2\' then 1 else 0 end  ) as numgrid
    
from
    ( select adddate(\'2018-10-01\', INTERVAL numlist.id month) as \'date\', 
        numlist.id 
    from ( select n100.i * 1 as id from num as n100 ) as numlist 
    where adddate(\'2018-10-01\', INTERVAL numlist.id month) <= \'2019-05-31\' ) years
    
left join building_resident_info bri on date_format(years.date, \'%Y-%m\')  = date_format(bri.entrytime, \'%Y-%m\') and bri.status=\'1\'

and bri. status = \'1\'
and bri.orgid like concat(\'37.02.82\', \'%\')
group by
    years.date
