Question

我很欣赏SQL小计的一些方向。我使用的是SQL Server 2008 R2。

使用的表：

OrderInvoiceHeader.ProvinceCode
OrderInvoiceHeader.InvoiceNumber
OrderInvoiceHeader.BillToCustomer
OrderInvoiceHeader.InvoiceDate
OrderInvoiceHeader.InvoiceAmount
OrderInvoiceHeader.GstAmount
OrderInvoiceHeader.PstAmount

Customer.BillToCustomer
Customer.CustomerName

CanadaProvinces.ProvinceCode
CanadaProvinces.ProvinceName

我必须在查询中显示：必须显示每个InvoiceNumber，ProvinceName，CustomerName，InvoiceDate，InvoiceAmount，GstAmount和PstAmount。必须通过ProvinceName包含小计，以包括InvoiceAmount，GstAmount和PstAmount的总和。必须包含所有省份的小计，以包括InvoiceAmount，GstAmount和PstAmount的总和。

序列必须是省名，客户名，发票编号。

Answer 1

就像我说的那样 - 分组：

select 
    InvoiceNumber   = case grouping(InvoiceNumber) when 1 then '<Total>' else InvoiceNumber end, 
    ProvinceName    = case grouping(ProvinceName) when 1 then '<Total>' else ProvinceName end, 
    CustomerName    = case grouping(CustomerName) when 1 then '<Total>' else CustomerName end, 
    InvoiceDate = case grouping(InvoiceDate) when 1 then '<Total>' else InvoiceDate, end  
    sum(InvoiceAmount), sum(GstAmount), sum(PstAmount)
from [table]
group by 
    grouping sets (
        (ProvinceName, InvoiceNumber, CustomerName, InvoiceDate),
        (ProvinceName),
        ()  -- grand total
    )

您可以使用rollup或cube来实现此目的，但您必须使用分组（[列]）来过滤掉不需要的聚合。

SQL小计，分组问题
