Question

Select
    CIDetail.Itemname, 
    sum(CIDetail.TaxAmount+ CIDetail.LineAmount) As [TotalAmount]  
From
    CIDetail (Nolock) 
    INNER JOIN CIHeader On CIDetail.InvoiceNo= CIHeader.InvoiceNo   
Where
    CIHeader.InvoiceDate Between '2010-04-01' AND '2014-04-01'
Group By 
    CIDetail.Itemname

Answer 1

将order by子句添加到查询中。在这里，正如您所说，您希望按日期，我将假设一个项目名称只有一个 InvoiceDate 。因此， max 将具有相同的值。您必须按照以下方式执行此操作

Select CIDetail.Itemname,

sum(CIDetail.TaxAmount+ CIDetail.LineAmount) As [TotalAmount],

From CIDetail (Nolock) INNER JOIN CIHeader

On CIDetail.InvoiceNo= CIHeader.InvoiceNo

Where CIHeader.InvoiceDate Between '2010-04-01' AND '2014-04-01' Group By

CIDetail.Itemname

Order By max(CIHeader.InvoiceDate) ASC

Answer 2

有一个派生表，您使用ANSI SQL的EXTRACT来获取日期部分，并同时添加金额。在主要级别，您GROUP BY同时为Itemname和year：

Select Itemname, "year", SUM(Amount) as TotalAmount
from
(
    CIDetail.Itemname, 
    extract(year from CIHeader.InvoiceDate) as "year",
    CIDetail.TaxAmount + CIDetail.LineAmount As Amount  
From
    CIDetail (Nolock) 
    INNER JOIN CIHeader On CIDetail.InvoiceNo= CIHeader.InvoiceNo   
) dt
Group By 
    Itemname, "year"

没有标记有问题的dbms，但如果您的dbms不支持EXTRACT，请尝试使用YEAR(CIHeader.InvoiceDate)或其他内容。

我想明年获取这些数据
