如何加入两个大的查询？

Question

这是我的第一个查询..

SELECT cmp.bundles_id, 
MONTH(cmp.payment_date) as month, 
sum(vb.bundle_price) as bundle_Price 
FROM `voice_bundles` as cmp 
join `voice_bundles_price` as vb 
ON cmp.bundles_id=vb.id 
GROUP BY MONTH(cmp.payment_date)

这是我的第二个问题..

SELECT 
MONTH(bill_due_date) as month, 
sum(charges) as Intercom,
sum(package_rent) as packages_price 
from `bill` 
GROUP BY MONTH(bill_due_date)

我想根据月份在同一个表格中显示数据...但问题是字段名称MONTH(bill_due_date) as month和MONTH(cmp.payment_date) as month

两个查询的月份相同..

如何组合两个查询并使其成为一个...并希望输出像这样？
