SQL Script按OrderNo分组所有数据？

Question

我加入了多个表格。我正在尝试通过OrderNo将数据分组。我的结果是重复行。如何将所有结果汇总到OrderNo？

SELECT     
tractor.id as Unit,
tractor.type_of,
orders.id as OrderNo, 
billing_history.delivery_date, 
orders.total_charge,
Case when movement.loaded = 'L' then movement.move_distance else 0 end as LoadedMiles,
Case when movement.loaded = 'E' then movement.move_distance else 0 end as EmptyMiles,  
billing_history.distance, 
billing_history.linehaul_chg, 
billing_history.other_charge, 
billing_history.total_charges, 
OrderPay, 
PerDiemPay,
TotalPay
from tractor

Left join billing_history 
on billing_history.tractor_id = tractor.id

Left join orders 
ON billing_history.order_id = orders.id

Left join 
(Select drs_settle_hist.order_id,   
sum(drs_settle_hist.order_pay) as OrderPay, 
sum(drs_settle_hist.perdiem_pay) as PerDiemPay, 
sum(drs_settle_hist.total_pay) as TotalPay
from drs_settle_hist 
where drs_settle_hist.is_void = 'N' 
group by 
drs_settle_hist.order_id) 
drs_settle_hist on orders.id = drs_settle_hist.order_id

Left join movement_order 
on billing_history.order_id = movement_order.order_id

Left join movement 
on movement_order.movement_id = movement.id


WHERE     orders.ordered_date  between '2013-01-01 00:00:00.000' and '2014-07-31 23:59:59.000'
and billing_history.delivery_date between '2014-07-01 00:00:00.000' and '2014-07-31         23:59:59.000' 
and tractor.type_of is not null 

以下是数据示例：

结果应如何：

Answer 1

我认为Distinct关键字可能对您有用，例如Distinct（orders.id）。

Answer 2

您只是在联接中对子选择进行分组。尝试对完整查询进行分组：

SELECT     
tractor.id as Unit,
tractor.type_of,
orders.id as OrderNo, 
billing_history.delivery_date, 
orders.total_charge,
Case when movement.loaded = 'L' then movement.move_distance else 0 end as LoadedMiles,
Case when movement.loaded = 'E' then movement.move_distance else 0 end as EmptyMiles,  
billing_history.distance, 
billing_history.linehaul_chg, 
billing_history.other_charge, 
billing_history.total_charges, 
OrderPay, 
PerDiemPay,
TotalPay
from tractor

Left join billing_history 
on billing_history.tractor_id = tractor.id

Left join orders 
ON billing_history.order_id = orders.id

Left join 
(Select drs_settle_hist.order_id,   
sum(drs_settle_hist.order_pay) as OrderPay, 
sum(drs_settle_hist.perdiem_pay) as PerDiemPay, 
sum(drs_settle_hist.total_pay) as TotalPay
from drs_settle_hist 
where drs_settle_hist.is_void = 'N' 
group by 
drs_settle_hist.order_id) 
drs_settle_hist on orders.id = drs_settle_hist.order_id

Left join movement_order 
on billing_history.order_id = movement_order.order_id

Left join movement 
on movement_order.movement_id = movement.id


WHERE     orders.ordered_date  between '2013-01-01 00:00:00.000' and '2014-07-31 23:59:59.000'
and billing_history.delivery_date between '2014-07-01 00:00:00.000' and '2014-07-31         23:59:59.000' 
and tractor.type_of is not null

group by OrderNo
