Question

我有一个Windows窗体应用程序，其中有许多值已成功写入我的数据库。它使用DataSet和所有常用的自动生成的表适配器等。我没有摆弄任何这些。我只是将我的字段从DataSources选项卡拖放到我的表单上。自动生成的SQL看起来很正常。

我有两个DateTimePicker控件数据以相同的方式绑定，如果我使用默认值，它们都不会写入数据库。 SQL Server中的数据格式是datetime。

从表单加载方法我正在设置这样的初始日期值。

// Set the Date entered to Today
dateTimePickerDateEntered.Value = DateTime.Now;

// Set the call back date to Today + 7 days
dateTimePickerCallBackDate.Value = DateTime.Now.AddDays(7);

如果我使用datetimepicker控件手动更改日期，则会成功保存到数据库。我确实谷歌这个问题，并找到了解决方案，提出了我已经在做的事情。

默认值在屏幕上看起来不错，如果我今天真的选择，它似乎没有改变。

我应该采取哪些不同的想法？

更新

我使用默认日期执行了保存，并使用名为SQL Profile Express的工具从服务器捕获生成的sql。

执行了三个命令。

exec sp_resetConnection

exec sp_executesql Insert

exec sp_executesql更新

我不确定为什么要进行更新。它似乎试图更新现有的无关记录，我正在插入一条新记录。主键文件QuoteID是一个标识字段。

这是插入

然后我再次做了相同的事情，但这次将日期设置在日期时间选择器中，而不是将它们保留在我的默认日期。我明天（2017年5月19日）选择了截止日期和2017年5月26日的回拨日期。这次除了输入日期之外的所有字段都被插入到数据库中。

就是这么清楚。这次CallBackDate工作，Dated Entered没有。

生成相同的三个命令，重置，插入和更新

有人能发现这里发生了什么吗？

查看捕获的SQL的更新部分对我来说完全没有意义。参数中的详细信息用于完全不同的记录。我正在创建一个ID为2122或者其中的新记录，并且更新的记录是ID 19.果然，如果我查看ID为19的记录，我看到真正的旧数据〜2006年已经更新了2017年日期。视觉工作室究竟如何提出这个SQL？

更奇怪的是，它总是更新记录ID 19，这是表中的第一条记录。

Answer 1

从我所看到的：

插入1 @DateEntered = NULL
更新1 @DateEntered = 2017-05-18 10：36：54.657
插入2 @DateEntered = 2017-05-19 11:38:53
更新2 @DateEntered = 2017-05-18 11：38：53.353。

在没有看到代码的情况下我无法确定，但我假设您在为@DateEntered设置参数的位置不正确。

Answer 2

我无法相信这是多么简单。

我的FormMainLoad看起来像这样。

1）填写我的数据集（第一条记录作为当前记录加载）

2）设置我的默认日期（猜猜它改变了第一条记录）

3）将对话框设置为开始新记录。

Bingo：他们的顺序错误

当我去保存时，它会对第一条记录进行更新，并在新记录上进行插入。

    private void FormMain_Load(object sender, EventArgs e)
    {
        // This line of code loads data into the 'quoteDataSet.Quote' table. You can move, or remove it, as needed.
        this.quoteTableAdapter.Fill(this.quoteDataSet.Quote);

        // Set the Date entered to Today
        dateTimePickerDateEntered.Value = DateTime.Now;

        // Set the call back date to Today + 7 days
        dateTimePickerCallBackDate.Value = DateTime.Now.AddDays(7);

        //Start the dialog in Add New Record Mode
        this.quoteBindingNavigator.Items["bindingNavigatorAddNewItem"].PerformClick();
    }

所以我将命令的顺序改为

1）加载数据集

2）设置对话框以开始新记录

3）设置默认日期

它有效。有趣的是我假设问题是日期时间选择器让我开始疯狂追逐。再加上我最初没有注意到第一条记录正在更新。

    private void FormMain_Load(object sender, EventArgs e)
    {
        // This line of code loads data into the 'quoteDataSet.Quote' table. You can move, or remove it, as needed.
        this.quoteTableAdapter.Fill(this.quoteDataSet.Quote);

        //Start the dialog in Add New Record Mode
        this.quoteBindingNavigator.Items["bindingNavigatorAddNewItem"].PerformClick();

        // Set the Date entered to Today
        dateTimePickerDateEntered.Value = DateTime.Now;

        // Set the call back date to Today + 7 days
        dateTimePickerCallBackDate.Value = DateTime.Now.AddDays(7);
    }

感谢所有评论的人。回答你的问题迫使我更加努力地看待我的代码并逐步加深它，直到答案击中我的脸。
