Question

我使用以下数据透视表来计算每月的销售额。

mon_pay_amount用于付款金额。我在tbl_orders表中还有一个列，其中包含应用的任何折扣mon_order_discount。

我需要能够将每月的折扣加起来，并将它们从每月的总付款金额中扣除。事后看来，应该在支付表中记录折扣，这可能会使这更容易！

PIVOT表和销售报告的新手，任何人都知道任何好的教程，到目前为止使用和修改示例已经得到了!!

数据说明

Table Name     ID              FK                  Columns
---------------------------------------------------------------------
tbl_orders     uid_orders                          mon_order_discount
tbl_payment    uid_payment     uid_pay_orderid     mon_pay_amount

数据

Data:          Jan      Feb      March
Discounts:     10.00    20.00    10.00 
Payments:      200.00   300.00   400.00

结果

Data:                Jan      Feb      March
Totals-Discount:     190.00   280.000  390.00

查询

SELECT *
FROM
  (SELECT 
      DATENAME(month, dte_pay_paydate) mth,
      mon_pay_amount
  FROM 
      tbl_payment
  INNER JOIN 
      dbo.tbl_orders ON (uid_pay_orderid = uid_orders)
  WHERE 
      bit_pay_paid = 1 
      AND txt_pay_descrip <> 'Credit' 
      AND uid_order_webid = 1
) x
PIVOT
(
  SUM(mon_pay_amount)
  FOR 
     mth IN ([January], [February], [March], [April], [May],
             [June], [July], [August], September, [October], 
             [November], [December])
) p

非常感谢

您可以在查询中计算正确的金额，类似于：

SELECT *
FROM
(
  SELECT 
      DATENAME(month, p.dte_pay_paydate) mth,
      p.mon_pay_amount - o.mon_order_discount as Total
  FROM tbl_payment p
  INNER JOIN tbl_orders o 
    ON p.uid_pay_orderid = o.uid_orders
  WHERE bit_pay_paid = 1 
      AND txt_pay_descrip <> 'Credit' 
      AND uid_order_webid = 1
) x
PIVOT
(
  SUM(Total)
  FOR 
     mth IN ([January], [February], [March], [April], [May],
             [June], [July], [August], September, [October], 
             [November], [December])
) p

编辑，根据您的评论，我认为以下内容可能有效：

SELECT *
FROM
(
  SELECT DATENAME(month, p.dte_pay_paydate) mth,
      sum(p.mon_pay_amount) - TotalDiscByMonth Total
  FROM tbl_payment p
  INNER JOIN tbl_orders o1
    on p.uid_pay_orderid = o1.uid_orders
  INNER JOIN
  (
    select sum(mon_order_discount) TotalDiscByMonth, DATENAME(month, dte_order_stamp) mth
    from tbl_orders
    group by DATENAME(month, dte_order_stamp)
  ) o2
    ON DATENAME(month, o1.dte_order_stamp) = o2.mth
  WHERE bit_pay_paid = 1 
      AND txt_pay_descrip <> 'Credit' 
  group by DATENAME(month, p.dte_pay_paydate), TotalDiscByMonth
) x
PIVOT
(
  SUM(Total)
  FOR 
     mth IN ([January], [February], [March], [April], [May],
             [June], [July], [August], September, [October], 
             [November], [December])
) p
