添加两个mysql查询的结果

Question

如何汇总下面两个查询的结果？

select firstname, surname, COUNT(*) as Built 
from  orders 
     join users on orders.builder = users.id 
where bStop > 1461496211 and bStop < 1461582649 
group by users.id; 


select firstname, surname, COUNT(*) as Built 
from production_points 
     join users on production_points.rewarded = users.id 
where Date(datetime) = '2016-04-25' 
group by users.id 

相同的用户可以在两个表中，所以我要总结他的研究结果，不想两条独立的线路，即显示4和第二个6就总10

Answer 1

如建议通过你们的研究后，这里是解决方案：

select uid, firstname, surname, Count(*) as Built from (
select users.id as uid, firstname, surname from orders join users on orders.builder = users.id where bStop > 1461542400 and bStop < 1461592622 
union all 
select users.id as uid, firstname, surname from production_points join users on production_points.rewarded = users.id where Date(datetime) ='2016-04-25' 
) performance group by uid; 

Answer 2

您可以使用第一个联盟。 如果这是mysql，您可以在此处看到它的语法：http://dev.mysql.com/doc/refman/5.7/en/union.html

它与其他数据库供应商类似。

Answer 3

你可能会得到每个的结果，并将它们分配给不同的变量。

并总结变量。
