第一步，求兩個表各自的數據
select DATE(a.create_date) as ‘nianfen‘,
sum(IF(a.type="0",1,0)) AS "shanghu",
SUM(IF(a.type="1",1,0)) AS "banzu",
SUM(IF(a.type="2",1,0)) AS "company",
0 as ‘zhaogong‘,
0 as ‘zhaohuo‘,
0 as ‘gongqiu‘,
0 as ‘gongcheng‘,
0 as ‘jianshe‘,
0 as ‘tujian‘,
0 as ‘advert‘,
0 as ‘dianqi‘,
0 as ‘yuanlin‘
from
dp_info a where DATE_FORMAT(create_date,‘%Y-%m‘)=‘2018-05‘
group by DATE(a.create_date)

union all

select DATE(a.date) as ‘nianfen‘,
0 as ‘shanghu‘,
0 as ‘banzu‘,
0 as ‘company‘,
sum(IF(a.to_type="招工信息",1,0)) AS "zhaogong",
SUM(IF(a.to_type="找活信息",1,0)) AS "zhaohuo",
SUM(IF(a.to_type="供求信息",1,0)) AS "gongqiu",
SUM(IF(a.to_type="工程機械",1,0)) AS "gongcheng",
SUM(IF(a.to_type="建設服務",1,0)) AS "jianshe",
SUM(IF(a.to_type="土建材料",1,0)) AS "tujian",
SUM(IF(a.to_type="裝修材料",1,0)) AS "advert",
SUM(IF(a.to_type="電氣材料",1,0)) AS "dianqi",
SUM(IF(a.to_type="園林景觀",1,0)) AS "yuanlin"
from
fb_fabu a where DATE_FORMAT(date,‘%Y-%m‘)=‘2018-05‘
group by DATE(a.date)

第二步，求兩個表合在一起的數據
select
xx.nianfen as ‘nianfen‘,
sum(xx.zhaogong) as "zhaogong",
sum(xx.zhaohuo) as ‘zhaohuo‘,
sum(xx.gongqiu) as ‘gongqiu‘,
sum(xx.gongcheng) as ‘gongcheng‘,
sum(xx.jianshe) as ‘jianshe‘,
sum(xx.shanghu) as ‘shanghu‘,
sum(xx.company) as ‘company‘,
sum(xx.banzu) as ‘banzu‘,
SUM(xx.tujian) AS "tujian",
SUM(xx.advert) AS "advert",
SUM(xx.dianqi) AS "dianqi",
SUM(xx.yuanlin) AS "yuanlin",
SUM(xx.tujian) AS "tujian"
SUM(IF(a.to_type="園林景觀",1,0)) AS "yuanlin"
from
(

) xx
GROUP BY xx.nianfen

第三步，求和
select
‘總計‘ as ‘nianfen‘,
sum(ddd.zhaogong) as "zhaogong",
sum(ddd.zhaohuo) as ‘zhaohuo‘,
sum(ddd.gongqiu) as ‘gongqiu‘,
sum(ddd.gongcheng) as ‘gongcheng‘,
sum(ddd.jianshe) as ‘jianshe‘,
sum(ddd.shanghu) as ‘shanghu‘,
sum(ddd.company) as ‘company‘,
sum(ddd.banzu) as ‘banzu‘,
SUM(ddd.tujian) AS "tujian",
SUM(ddd.advert) AS "advert",
SUM(ddd.dianqi) AS "dianqi",
SUM(ddd.yuanlin) AS "yuanlin"
from
(
