c# - SQL 查询正在复制行并在我的聚合函数中使用这些行

Question

您好，抱歉，这可能是一个很长的问题，我有一个奇怪的问题突然出现了。我正在尝试创建一个类似会计的应用程序，其中几个列按它们所属的组聚合。但是，其中一些列可能包含我不想包含在总数中的重复数据。

我的桌子看起来像：

CREATE TABLE [dbo].[RawDataTable] (
[Id]                     INT             IDENTITY (1, 1) NOT NULL,
[CheckDate]              DATE            NULL,
[PropNum]                INT             NOT NULL,
[PropSeqNum]             INT             NULL,
[PropName]               NVARCHAR (100)  NOT NULL,
[ProductionMonth]        INT             NULL,
[Product]                INT             NOT NULL,
[LeaseVolume]            DECIMAL (18, 2) NOT NULL,
[Price]                  DECIMAL (18, 2) NOT NULL,
[LeaseGrossValue]        DECIMAL (18, 2) NOT NULL,
[LeaseTaxes]             DECIMAL (18, 2) NULL,
[LeaseOtherDeductions]   DECIMAL (18, 2) NOT NULL,
[LeaseNetValue]          DECIMAL (18, 2) NOT NULL,
[DisbursementDecimal]    DECIMAL (18)    NULL,
[InterestType]           NVARCHAR (10)   NULL,
[InterestGrossValue]     DECIMAL (18, 2) NOT NULL,
[InterestTaxes]          DECIMAL (18, 2) NOT NULL,
[IntrestOtherDeductions] DECIMAL (18, 2) NOT NULL,
[InterestNetValue]       DECIMAL (18, 2) NOT NULL,
PRIMARY KEY CLUSTERED ([Id] ASC)
);

首先，我尝试使用此存储过程删除任何重复数据：

CREATE PROCEDURE [dbo].[EraseDuplicates]
AS
UPDATE  T1
SET     T1.LeaseVolume = 0,
        T1.Price = 0,
        T1.LeaseGrossValue = 0,
        T1.LeaseTaxes = 0,
        T1.LeaseOtherDeductions = 0,
        T1.LeaseNetValue = 0
FROM
    (SELECT  *
     FROM    RawDataTable
     WHERE   Product >= 400 OR
             Id NOT IN 
                (SELECT MIN(Id)
                 FROM RawDataTable
                 GROUP BY CheckDate, PropNum, PropSeqNum, PropName, ProductionMonth, Product)) AS T1

当我从 EraseDuplicates 存储过程返回时，我的问题出现了，它正确地将数据清零，但是它也在复制行并将它们添加回表中，结果如下：

主要编辑

我已将其范围缩小到此存储过程。一旦我从这种方法返回

public static void EraseDuplicateData(string connString)
    {
        using (IDbConnection db = new SqlConnection(ConfigurationManager.ConnectionStrings[connString].ConnectionString))
        {
            db.Query("EraseDuplicates", commandType: CommandType.StoredProcedure);
        }
    }

数据库突然复制了行。这些值被正确归零，但我只是不明白更新命令如何创建行。

好吧，这只是我的一个愚蠢的错误。我有一个触发两次的拖放事件，因为我以编程方式在我的 Form_Load 中声明了它，并且它也在我的表单设计器中声明。它花了比我愿意承认的时间更长的时间来解决这个问题（但你可能可以从发布时间到我提交这个时间）。

对于遇到此问题的其他任何人，如果您的代码中有类似的内容：

AllowDrop = true;
DragEnter += new DragEventHandler(Form1_DragEnter);
DragDrop += new DragEventHandler(Form1_DragDrop);

检查表单的设计器是否有类似的东西。尝试从您的代码中注释它，看看它是否修复它。

也只想对任何试图帮助我的人说声谢谢！
