Question

给定日期，该表格显示该日期售出的物品。

该表将项目的类别分组，并显示每个类别的总销售额。最后，报告显示当天的总销售额。像这样：

ID    Category  Price   Units   Total Value
----------------------------------------------------
2244    class   10.50    10       105.00   
2555    class   5.00      5       25.00   
3455    class   20.00     1       20.00   

  Total                  16       150.00    

1255    pop     20.00     5       100.00
5666    pop     10.00    10       100.00

  Total                  15       200,00

1244    rock    2.50     20       50.00   
8844    rock    5.00     50       250.00   

  Total                  70       300.00

----------------------------------------------

Total Daily     Sales   101       650.00

DBMS：SQL Server 2012

Bolded：主键

项目（ upc ，标题*，类型，类别，公司，年份，价格，库存）
PurchaseItem（ receiptId ， upc ，数量）
订单（ receiptId ，日期，cid，卡＃，expiryDate，expectedDate，deliverDate）

Rough work of what I have so far..

SELECT I.upc, I.category, I.price, P.quantity, P.quantity*I.price AS totalValue, SUM(totalValue), SUM(P.quantity) AS totalUnits, O.date
FROM Item I, Order O
JOIN (SELECT P.quantity
      FROM PurchaseItem P, Item I
      WHERE I.upc = P.upc)
ON I.upc = P.upc
WHERE O.date = ({$date}) AND O.receiptId = P.receiptId
GROUP BY I.upc, I.category, I.price, P.quantity, totalValue, O.date

好吧，这不对，我有点卡住了。需要一些帮助！
我想要它所以它从一个类别产生项目的总价值，然后在最后，它将累计所有类别的项目的总价值。

示例表格
项目（2568，Beatles，rock，Music Inc，1998,50.50,5000）
PurchaseItem（5300,2568,2）
订单（5300，10/09/2014，...不重要..）cid是customerId，card＃是信用卡号。

Answer 1

SSRS或类似的报告包通常可以为您本地处理此问题。如果必须在SQl脚本中完成，那么快速解决方案将是游标/ while循环。伪代码看起来像这样;

create tempsales table;
get distinct list of categories;

for each category
Begin
  insert into tempsale (...)
  sales where category = @category 
  group by category, item

  insert into tempsales (...) -- use NULL value for item or perhaps a value of 'TOTAL'
  Sales where category = @category
  group by category

  when last category 
  insert into tempsales (...) -- use NULL value for item AND Category or perhaps a value of 'TOTAL'
  total with no group
end

 select from tempsales;

创建示例数据

use tempdb;

create table Item(
    upc         int,
    category    varchar(100),
    price       decimal(8,2)
)
create table PurchaseItem(
    receiptId   int,
    upc         int,
    quantity    int
)
create table [Order](
    receiptId   int,
    [date]      date
)

insert into Item values
(2244, 'class', 10.50),
(2555, 'class', 5.0),
(3455, 'class', 20.0),
(1255, 'pop', 20.0),
(5666, 'pop', 10.0),
(1244, 'rock', 2.50),
(8844, 'rock', 5.0)

insert into PurchaseItem values
(5300, 2244, 10),
(5300, 2555, 5),
(5300, 3455, 1),
(5300, 1255, 5),
(5300, 5666, 10),
(5300, 1244, 20),
(5300, 8844, 50)

insert into [Order] values(5300,'20140910')

        when grouping(Id) = 1 then 'Total'
        else Category
