已开具发票的付款总计

Question

我有以下表格：

create table Invoices (InvoiceID int, InvoiceDate date, Total money);
insert into Invoices (InvoiceID, InvoiceDate, Total) values
(1,'2020-11-01', 20),
(2,'2020-11-01', 14),
(3,'2020-11-02', 40),
(4,'2020-11-02', 35),
(5,'2020-11-03', 10),
(6,'2020-11-04', 63),
(7,'2020-11-04', 42);
   
create table Payments (InvoiceID int, PaymentDate date, Total money);
insert into Payments (InvoiceID, PaymentDate, Total) values
(5,'2020-11-07', 10),
(6,'2020-11-08', 63),
(4,'2020-11-09', 35),
(2,'2020-11-10', 14),
(7,'2020-11-11', 42),
(11,'2020-11-13', 20),
(13,'2020-11-14', 15);

要使用 SQL Server 2005 获得运行总计，我使用以下脚本：

with DateRange as
(
  select convert(date, '2020-11-01') as DateValue
  union all
  select dateadd(day, 1, dr.DateValue)
  from DateRange dr
  where dr.DateValue < '2020-11-30'
),
InvoicedTotal as
(
  select dr.DateValue,
         isnull(sum(i.Total), 0) as Invoiced
  from DateRange dr
  left join Invoices i
    on i.InvoiceDate = dr.DateValue
  group by dr.DateValue
),
PaidTotal as
(
  select dr.DateValue,
         isnull(sum(p.Total), 0) as Paid
  from DateRange dr
  left join Payments p
    on p.PaymentDate = dr.DateValue
  group by dr.DateValue
)
select convert(varchar(10), dr.DateValue, 102) as [YYYY.MM.DD],
       it1.Invoiced as [Invoiced],
       it3.Invoiced as [CumInvoiced],
       pt1.Paid as [Paid],
       pt3.Paid as [CumPaid],
       it3.Invoiced - pt3.Paid as [RunningTotal]
from DateRange dr
join InvoicedTotal it1
  on it1.DateValue = dr.DateValue
join PaidTotal pt1
  on pt1.DateValue = dr.DateValue
cross apply ( select sum(it2.Invoiced) as Invoiced
              from InvoicedTotal it2
              where it2.DateValue <= dr.DateValue ) it3
cross apply ( select sum(pt2.Paid) as Paid
              from PaidTotal pt2
              where pt2.DateValue <= dr.DateValue ) pt3
order by dr.DateValue;

如何在报告中仅显示在指定时间范围内已开具发票的付款？

order by dr.DateValue;
