格式:
select sum(t1.字段1), 计算2,t1.字段2
from 表1 t1
inner join
(select sum(t2字段2) as 计算2
from 表2
group by t2.关键字1) t2
on t1.id = t2.id
group by t1.字段2,计算2
关键是第一个select的group by 语句要放在后面
例:
select t1.id,trydate0
,sum(ProcessNeedMinutes) as TotalMinutes ,DoneMinutes
from tb_partprocess t1
inner join tb_order od on od.id = t1.id
left join
(select sum(ProcessNeedMinutes) as DoneMinutes
from tb_partprocess pp where startdate is not null and enddate is not null
group by pp.id) as t2
on t1.id = t2.id
where
TryDate0>='2012-5-1 0:00:00' and TryDate0<='2012-6-1 0:00:00'
group by t1.id,t1.partno,TryDate0,DoneMinutes
