1、時間字段是datetime類型
2、需要用到中間表，表結構和數據鏈接下載

3、前兩個 adddate 月日需要在代碼中寫死 從每年的-01-01開始，-最后一個日期同理xxxx-12-31
4、下面是sql
select concat(month(years.date),'月') as year, years.date, date_format(years.date, '%Y-%m') AS years, sum( case when bri.status = '1' then 1 else 0 end ) as num, -- 總數 sum( case when bri.status = '1' and bri.sex='1' then 1 else 0 end ) as numman, -- 男性數量 sum( case when bri.status = '1' and bri.sex='2' then 1 else 0 end ) as numgrid -- 女性數量 from ( select adddate('2018-01-01', INTERVAL numlist.id month) as 'date', numlist.id from ( select n100.i * 1 as id from num as n100 ) as numlist where adddate('2018-01-01', INTERVAL numlist.id month) <= '2018-12-31' ) 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、效果圖如下
附帶：
1、還有一種寫法，是把12個月寫死的
sql:
select case month(bri.entrytime) when '1' then sum(bri.status) else 0 end as 1月, case month(bri.entrytime) when '2' then sum(bri.status) else 0 end as 2月, case month(bri.entrytime) when '3' then sum(bri.status) else 0 end as 3月, case month(bri.entrytime) when '4' then sum(bri.status) else 0 end as 4月, case month(bri.entrytime) when '5' then sum(bri.status) else 0 end as 5月, case month(bri.entrytime) when '6' then sum(bri.status) else 0 end as 6月, case month(bri.entrytime) when '7' then sum(bri.status) else 0 end as 7月, case month(bri.entrytime) when '8' then sum(bri.status) else 0 end as 8月, case month(bri.entrytime) when '9' then sum(bri.status) else 0 end as 9月, case month(bri.entrytime) when '10' then sum(bri.status) else 0 end as 10月, case month(bri.entrytime) when '11' then sum(bri.status) else 0 end as 11月, case month(bri.entrytime) when '12' then sum(bri.status) else 0 end as 12月 from building_resident_info bri where date_format(bri.entrytime, '%Y') = '2018' and bri.orgid like concat('37.02.82.01', '%') and bri.status='1'
效果：
如有疏漏，請指正！謝謝。
