Question

我有这个查询

select dbo.CLOI_ClientOrderItems.cl_id,
count(dbo.IN_Invoices.MasterOrderId) as Orders,
OverallTotal = (select sum(in_total) from IN_Invoices where datepart(mm,in_date_issued)=2 and datepart(yyyy,in_date_issued)=2014)
from IN_Invoices
inner join CLOI_ClientOrderItems on IN_Invoices.MasterOrderId=CLOI_ClientOrderItems.MasterOrderId
where datepart(mm,in_date_issued)=2 and datepart(yyyy,in_date_issued)=2014
group by cl_id

结果

cl_id         orders overalltotoal 
100000pro       5       39949
100001pro       64      39949

结果显示两个订单都相同我需要显示特定cl_id订单的总计..

Answer 1

试试这个

select dbo.CLOI_ClientOrderItems.cl_id,f.MasterOrderId as orders ,f.in_total as total
   from(select sum(in_total),count(MasterOrderId) from IN_Invoices where datepart(mm,in_date_issued)=2 and datepart(yyyy,in_date_issued)=2014 group by cl_id)as f,IN_Invoices
   inner join CLOI_ClientOrderItems on IN_Invoices.MasterOrderId=CLOI_ClientOrderItems.MasterOrderId
where datepart(mm,in_date_issued)=2 and datepart(yyyy,in_date_issued)=2014
group by cl_id

Answer 2

如果没有架构来测试它，很难看出是否有效，但是看到你已经在OverallTotal的计算中添加了WHERE子句，这可能会对你有所帮助：

select 
 dbo.CLOI_ClientOrderItems.cl_id,
 count(dbo.IN_Invoices.MasterOrderId) as Orders,
 sum(in_total) AS OverallTotal
from IN_Invoices
 inner join CLOI_ClientOrderItems on   
 IN_Invoices.MasterOrderId=CLOI_ClientOrderItems.MasterOrderId
where datepart(mm,in_date_issued)=2 and datepart(yyyy,in_date_issued)=2014
group by cl_id

如果没有，请提供您的架构和一些数据的方式。
