1、時間欄位是datetime型別

2、需要用到中間表，表結構和資料鏈接下載

3、前兩個 adddate 日需要在資料庫寫死 從每日的-01開始，-最後一個日期同理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

5、結果

如有疏漏，請指正！謝謝。
