基于分销商代码生成订单号

Question

我需要根据分销商代码生成订单号，如下所示。 订单号格式如下

订单号：分销商代码/零售商代码/TO/DDMMYY订单号（订单号将为 0001,0002，...）

Scenario 1  Order Uploaded Console time: 11AM (08-Jan'22)
Retailer 1  22520/1400002/TO/0801220001
Retailer 2  22520/1400003/TO/0801220002
Retailer 3  22520/1400004/TO/0801220003
Retailer 4  22520/1400005/TO/0801220004
Retailer 5  22520/1400006/TO/0801220005
Retailer 6  22520/1400007/TO/0801220006

Same Distributor different retailers. Order number carries forward Distributor  wise and not retailer wise.

和

Scenario 2  Order Uploaded Console time 2PM (08-Jan'22)
Retailer 1  22520/1400002/TO/0801220007
Retailer 2  22520/1400003/TO/0801220008
Retailer 7  22520/1400011/TO/0801220009
Retailer 8  22520/1400012/TO/0801220010

Same Distributor different retailers and same retailers. For same retailers for the "same product" same or unique quantity gets uploaded.

和

Scenario 3  Order Uploaded Console time 10AM (14-Jan'22)
Retailer 4  22520/1400005/TO/1401220011
Retailer 5  22520/1400006/TO/1401220012
Retailer 6  22520/1400007/TO/1401220013
Retailer 8  22520/1400012/TO/1401220014

Same Distributor different day order was uploaded. Please note the series

我已使用以下 SP 将 EXCEL 中的一些数据上传到数据库

CREATE PROC [dbo].[Proc_TeleOrderUpload]    
(                              
@ORDER_UPLOAD NTEXT = NULL,              
@UserId INT = 0                                                     
)                        
AS                                 
BEGIN
DECLARE @idoc AS INT
    Create Table #Tbl_TeleOrderUpload
    (
        DistCode NVARCHAR(50),  
        CompRtrCode NVARCHAR(50),                       
        ProductCode NVARCHAR(50),
        QtyInPieces Varchar(10),
        errStatus INT
    )

     EXEC sp_xml_preparedocument @idoc OUTPUT, @ORDER_UPLOAD

     INSERT INTO #Tbl_TeleOrderUpload
     SELECT  
        DistCode,   
        CompRtrCode,                       
        ProductCode,
        QtyInPieces,
        0 AS errStatus    
    FROM OPENXML (@idoc, '/TeleOrderUpload/Record',2)
    WITH                           
    (                
        DistCode NVARCHAR(50),  
        CompRtrCode NVARCHAR(50),                       
        ProductCode NVARCHAR(50),
        QtyInPieces Varchar(10)
    )

    EXEC sp_xml_removedocument @idoc

      INSERT INTO Tbl_TeleOrderUpload
        (
            DistCode,
            CompRtrCode,
            ProductCode,
            QtyInPieces,
            OrderTaken,
            OrderNumber,
            UploadFlag,
            CreatedId,
            CreatedDate  
        )
        SELECT DISTINCT 
            DistCode,
            CompRtrCode,
            ProductCode,
            CAST(QtyInPieces AS int),
            'Console',
            '',
            'Y',
            @UserId,    
            GETDATE()
        FROM
         #Tbl_TeleOrderUpload

         SELECT 'DATA UPLOADED SUCCESSFULLY...'
END 

在此，我需要插入上面的订单号。 这里cursor不应该用来更新订单号。 我需要实现以下逻辑

DECLARE @number AS INT =  0
SET @number = (SELECT MAX(RIGHT(OrderNumber,6)) FROM Tbl_TeleOrderUpload WHERE DistCode=@DistCode)

IF @number IS NULL
SET @number=1
ELSE
SET @number =@number+1

SELECT RIGHT('000000' + CAST(@number AS VARCHAR(6)) , 6)

样本数据如下：

CREATE TABLE [dbo].[Tbl_TeleOrderUpload](
[DistCode] [nvarchar](50) NULL,
[CompRtrCode] [nvarchar](50) NULL,
[ProductCode] [nvarchar](50) NULL,
[QtyInPieces] [int] NULL,
[OrderTaken] [varchar](10) NULL,
[OrderNumber] [varchar](100) NULL,
[UploadFlag] [varchar](10) NULL,
[CreatedId] [int] NULL,
[CreatedDate] [datetime] NULL
)


INSERT INTO Tbl_TeleOrderUpload VALUES ('0000014811','148111600220','GNOTNA06',1,'Console','','Y',1,GETDATE())
INSERT INTO Tbl_TeleOrderUpload VALUES ('0000014811','148111600220','GNOTNA06',2,'Console','','Y',1,GETDATE())
INSERT INTO Tbl_TeleOrderUpload VALUES ('0000014811','148111600220','GNOTNA06',3,'Console','','Y',1,GETDATE())
INSERT INTO Tbl_TeleOrderUpload VALUES ('0000014811','148111600220','GNOTNA06',4,'Console','','Y',1,GETDATE())
INSERT INTO Tbl_TeleOrderUpload VALUES ('0000014811','148111600220','GNOTNA06',5,'Console','','Y',1,GETDATE())
INSERT INTO Tbl_TeleOrderUpload VALUES ('0000015000','15001600220','GNOTNA06',1,'Console','','Y',1,GETDATE())
INSERT INTO Tbl_TeleOrderUpload VALUES ('0000015000','150011600220','GNOTNA06',2,'Console','','Y',1,GETDATE())
INSERT INTO Tbl_TeleOrderUpload VALUES ('0000015000','15001600220','GNOTNA06',3,'Console','','Y',1,GETDATE())
INSERT INTO Tbl_TeleOrderUpload VALUES ('0000015000','15001600220','GNOTNA06',4,'Console','','Y',1,GETDATE())
INSERT INTO Tbl_TeleOrderUpload VALUES ('0000015000','150011600220','GNOTNA06',5,'Console','','Y',1,GETDATE())

请指导我实现这一目标。

我的 SQL SERVER 版本是

Microsoft SQL Server 2008 R2 (RTM) - 10.50.1617.0 (X64) Standard Edition (64-bit) on Windows NT 6.1 (Build 7601: Service Pack 1) (Hypervisor)

Answer 1

看起来ROW_NUMBER()在 SQL 2008 中有效，所以这可能是您想要的：

SELECT *, RIGHT('000000' + CAST(@MyOrderNumber AS VARCHAR(6)) , 6)
FROM (
    SELECT *, ROW_NUMBER() OVER (PARTITION BY DistCode ORDER BY CompRtrCode) As MyOrderNumber
    FROM Table
) ST

我敢肯定，您的要求远不止这些。

这将从统计数据集中生成一些订单号。 如果您愿意，您可以使用它来更新表格 go。

但它不考虑新记录的出现。 当新记录出现在现有记录的中间时，它绝对没有考虑到

这就是为什么像这样使用特殊的人工生成的 id 是个坏主意。

如果您希望能够基于现有记录并从那里增加订单号，则解决方案会更加复杂。

SELECT ST.*, RIGHT('000000' + CAST(ST.MyOrderNumber + ISNULL(CN.HighestOrderNo) AS VARCHAR(6)) , 6)
FROM (
    SELECT *, ROW_NUMBER() OVER (PARTITION BY DistCode ORDER BY CompRtrCode) As MyOrderNumber
    FROM Table
) ST
LEFT JOIN
(
  SELECT DistCode, MAX(ExistingOrderNo) HighestOrderNo
  GROUP BY DistCode 
    FROM Table
) CN
ON CN.DistCode = ST.DistCode

但我必须重申：

根据这样的特殊规则生成密钥是一个坏主意，因为随着不同记录的到达，最终会出现间隙和不一致的数字。

特别是这种情况：

Retailer 4  22520/1400005/TO/1401220011
Retailer 5  22520/1400006/TO/1401220012
Retailer 6  22520/1400007/TO/1401220013
Retailer 8  22520/1400012/TO/1401220014

现在您导入同一天到达的下一批数据，它包含以下记录：

Retailer 6  22520/1400008/TO/140122

它应该有什么订单号？ 1400008 在 140007 之后，所以应该是 000014。但这已经被占用了。
