mysql 根据起止年月 查询所选年月的数据

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 日需要在数据库写死 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

5、结果

如有疏漏，请指正！谢谢。
