从 SQL Server 表计算销售额、退款和破损

Question

我有 4 个表，即 Products、SalesLog、Breakages、SalesReturn。

产品表

CREATE TABLE [dbo].[Products](
[ProductId] [int] IDENTITY(1,1) NOT NULL,
[pName] [nvarchar](30) COLLATE SQL_Latin1_General_CP1_CI_AS NULL,
[pSize] [int] NULL,
[pPrice] [decimal](10, 2) NULL,
[pPackQty] [int] NULL,
[pGroup] [int] NULL,
[pCode] [int] NULL,
[OpenStock] [int] NULL,
[CloseStock] [int] NULL,
[YrlyOpenStock] [int] NULL,
CONSTRAINT [PK_Products] PRIMARY KEY CLUSTERED 
(
[ProductId] ASC
)WITH (PAD_INDEX  = OFF, IGNORE_DUP_KEY = OFF) ON [PRIMARY]
) ON [PRIMARY]

销售记录表

CREATE TABLE [dbo].[SalesLog](
[SalesID] [int] IDENTITY(1,1) NOT NULL,
[MemoNo] [int] NULL,
[ProductCode] [int] NULL,
[Quantity] [int] NULL,
[Price] [decimal](10, 2) NULL,
[pGroup] [int] NULL,
[pName] [nvarchar](30) COLLATE SQL_Latin1_General_CP1_CI_AS NULL,
[pSize] [int] NULL,
[BillDate] [nchar](10) COLLATE SQL_Latin1_General_CP1_CI_AS NULL,
CONSTRAINT [PK_SalesLog] PRIMARY KEY CLUSTERED 
(
[SalesID] ASC
)WITH (PAD_INDEX  = OFF, IGNORE_DUP_KEY = OFF) ON [PRIMARY]
) ON [PRIMARY]

SalesReturn 表

CREATE TABLE [dbo].[SalesReturn](
[srID] [int] IDENTITY(1,1) NOT NULL,
[ProductCode] [int] NULL,
[Quantity] [int] NULL,
[pGroup] [int] NULL,
[MemoNo] [int] NULL,
[SalesmanID] [int] NULL,
[Price] [decimal](10, 2) NULL,
[JobShift] [int] NULL,
[BillDate] [nchar](10) COLLATE SQL_Latin1_General_CP1_CI_AS NULL,
[AddedOn] [datetime] NULL,
 CONSTRAINT [PK_SalesReturn] PRIMARY KEY CLUSTERED 
(
[srID] ASC
)WITH (PAD_INDEX  = OFF, IGNORE_DUP_KEY = OFF) ON [PRIMARY]
) ON [PRIMARY]

破损表

CREATE TABLE [dbo].[Breakages](
[breakId] [int] IDENTITY(1,1) NOT NULL,
[MemoNo] [int] NULL,
[SalesmanID] [int] NULL,
[ProductCode] [int] NULL,
[pName] [nvarchar](30) COLLATE SQL_Latin1_General_CP1_CI_AS NULL,
[Quantity] [int] NULL,
[Price] [decimal](10, 2) NULL,
[pGroup] [int] NULL,
[JobShift] [int] NULL,
[BillDate] [nchar](10) COLLATE SQL_Latin1_General_CP1_CI_AS NULL,
[AddedOn] [datetime] NULL,
CONSTRAINT [PK_Breakages_1] PRIMARY KEY CLUSTERED 
(
[breakId] ASC
)WITH (PAD_INDEX  = OFF, IGNORE_DUP_KEY = OFF) ON [PRIMARY]
) ON [PRIMARY]

我必须生成一个报告以按照以下模式显示特定日期的 SalesLOg、SalesReturn 和 Breakages（根据 SalesLog、Breakages 和 SalesReturn 的 BillDate 列）。

想要的输出

Code      ItemName     Price     SalesQty     BreakagesQty    SalesReturnQty
 1           A          $10         50              2               2
 1           A          $12         150             1               10
 15          X          $5          56              0               2
 20          Z          $8          121             0               0

为了阅读而减少了输出列

如您所见，由于产品“A”的价格变化，产品“A”已被列出两次。为此，我编写了一个查询：

SELECT     SalesLog.pName, SalesLog.ProductCode, MIN(ItemGroup.gName) AS GroupName, 
           SalesLog.Price, SUM    (SalesLog.Quantity) AS SalesQty, 
           SUM(SalesLog.Quantity * SalesLog.Price) AS SalesValue, 
     ISNULL ((SELECT     SUM(Quantity) AS Expr1 FROM Breakages
        WHERE (ProductCode = SalesLog.ProductCode) AND (Price = SalesLog.Price) AND 
          (BillDate = '07/01/2010') AND (pGroup <> 15) AND (pGroup <> 16)), 0) AS BreakQty, 
     ISNULL ((SELECT     SUM(Quantity * Price) AS Expr1
 FROM         Breakages
        WHERE     (ProductCode = SalesLog.ProductCode) AND (Price = SalesLog.Price) AND 
          (BillDate = '07/01/2010') AND (pGroup <> 15) AND (pGroup <> 16)), 0) AS BreakValue, 
     ISNULL ((SELECT     SUM(Quantity) AS Expr1
 FROM         SalesReturn
       WHERE     (ProductCode = SalesLog.ProductCode) AND (Price = SalesLog.Price) AND 
          (BillDate = '07/01/2010') AND (pGroup <> 15) AND (pGroup <> 16)), 0) AS ReturnQty, 
     ISNULL ((SELECT     SUM(Quantity * Price) AS Expr1
 FROM         SalesReturn
       WHERE     (ProductCode = SalesLog.ProductCode) AND (Price = SalesLog.Price) AND 
          (BillDate = '07/01/2010') AND (pGroup <> 15) AND (pGroup <> 16)), 0) AS ReturnValue, 
     ISNULL ((SELECT     SUM(Quantity) AS Expr1
 FROM         SalesLog
       WHERE     (ProductCode = Products.pCode)), 0) AS CummSales
 FROM         SalesLog 
          INNER JOIN
              ItemGroup ON ItemGroup.gCode = SalesLog.pGroup AND SalesLog.pGroup = ItemGroup.gCode 
          INNER JOIN
              Products ON Products.pCode = SalesLog.ProductCode
       WHERE  (SalesLog.BillDate = '07/01/2010') AND (SalesLog.pGroup <> 15) AND 
              (SalesLog.pGroup <> 16)
GROUP BY SalesLog.pName, SalesLog.ProductCode, SalesLog.Price, Products.pCode, Products.pPrice
ORDER BY SalesLog.ProductCode, SalesLog.pName

我对这个查询的问题是，它无法显示没有销售但有销售退货的项目条目。这个条件是我的客户给的。你能帮我解决这个问题吗？任何实现此条件的 t-sql 查询或逻辑都会有所帮助...

谢谢你包容我............

试试这样的：

SELECT  MIN(Products.pName) AS pName,
        Products.pCode AS ProductCode,
        MIN(Products.pGroup) AS GroupName, 
        Sales_Trans.Price,
        SUM(Sales_Trans.Sales_Qty) AS SalesQty, 
        SUM(Sales_Trans.Sales_Value) AS SalesValue, 
        SUM(Sales_Trans.Break_Qty) AS BreakQty, 
        SUM(Sales_Trans.Break_Value) AS BreakValue, 
        SUM(Sales_Trans.Return_Qty) AS ReturnQty, 
        SUM(Sales_Trans.Return_Value) AS ReturnValue, 
FROM Products
JOIN        
(SELECT ProductCode, Price, Quantity Sales_Qty, Price * Quantity Sales_Value, 0 Break_Qty, 0 Break_Value, 0 Return_Qty, 0 Return_Value FROM SalesLog
 WHERE  (BillDate = '07/01/2010') AND (pGroup <> 15) AND (pGroup <> 16)
 UNION ALL
 SELECT ProductCode, Price, 0 Sales_Qty, 0 Sales_Value, 0 Break_Qty, 0 Break_Value, Quantity Return_Qty, Price * Quantity Return_Value FROM SalesReturn
 WHERE  (BillDate = '07/01/2010') AND (pGroup <> 15) AND (pGroup <> 16)
 UNION ALL
 SELECT ProductCode, Price, 0 Sales_Qty, 0 Sales_Value, Quantity Break_Qty, Price * Quantity Break_Value, 0 Return_Qty, 0 Return_Value FROM Breakages
 WHERE  (BillDate = '07/01/2010') AND (pGroup <> 15) AND (pGroup <> 16)
) Sales_Trans
ON (Products.pCode = Sales_Trans.ProductCode) and (Products.pPrice = Sales_Trans.Price)
GROUP BY Products.pCode, Sales_Trans.Price
ORDER BY 2,1

（假设价格变化的完整历史存储在 Products 表中 - 如果只有最新价格存储在 Products 中，则 Products.pPrice = Sales_Trans.Price 连接条件将需要删除。）
