DateTimePicker 值未保存到 SQL 服务器数据库
DateTimePicker value not saved to SQL Server database
我有一个 Windows Forms 应用程序，其中许多值已成功写入我的数据库。它使用 DataSet 和所有常见的自动生成的 table 适配器等。我没有摆弄任何这些。我只是将我的字段从“数据源”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，它们都不会写到数据库中。 SQL服务器中的数据格式为日期时间。
从表单加载方法我设置初始日期值是这样的。
// 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，它会成功保存到数据库中。我做了 google 这个问题并找到了建议我已经在做的事情的解决方案。
默认值在屏幕上看起来不错，而且如果我今天实际选择，似乎也不会改变。
有什么不同的想法吗？
谢谢

更新
我使用默认日期执行保存并使用名为 SQL Profile Express 的工具从服务器捕获生成的 sql。
执行了三个命令。
执行sp_resetConnection
执行sp_executesql插入
执行sp_executesql更新
我不确定它为什么要进行更新。它似乎在尝试更新现有的不相关记录，而我正在插入一条新记录。
主键字段 QuoteID 是一个标识字段。
这是插页

然后我又做了几乎相同的事情，但这次在日期时间选择器中设置日期，而不是将它们保留在我的默认日期。
我选择明天（2017 年 5 月 19 日）作为输入日期，2017 年 5 月 26 日作为回拨日期。这次除了 Date Entered 之外的所有字段都被插入到数据库中。
这样就清楚了。这次 CallBackDate 有效，而 Dated Entered 没有。
生成了相同的三个命令，重置、插入和更新
有人能看出这是怎么回事吗？

更新 2
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。我正在创建一个新记录，其中 ID 为 2122 左右，更新的记录为 ID 19。果然，如果我查看 ID 为 19 的记录，我会看到非常旧的数据 ~ 2006 年已更新为我的 2017 年日期。
visual studio 到底是怎么想到这个 SQL 的？
更奇怪的是，它看起来总是更新记录 ID 19，这是 table 中的第一条记录。
据我所知：
- 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，但我假设您为 @DateEntered 设置参数的位置不正确。
我不敢相信这竟然如此简单。
我的 FormMainLoad 看起来像这样。
1) 填充我的数据集（第一条记录加载为当前记录）
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。
宾果游戏：顺序错误
当我保存时，它会更新第一条记录并插入新记录。
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();
}
所以我把命令的顺序改成了这样
1) 加载数据集
2) 设置对话框开始新记录
3) 设置默认日期
并且有效。有趣的是，我如何假设问题出在日期时间选择器上让我开始了疯狂的追逐。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);
}
感谢所有发表评论的人。
回答您的问题迫使我更加认真地审视我的代码，并逐步更慢地深入了解代码，直到答案让我眼前一亮。
我有一个 Windows Forms 应用程序，其中许多值已成功写入我的数据库。它使用 DataSet 和所有常见的自动生成的 table 适配器等。我没有摆弄任何这些。我只是将我的字段从“数据源”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，它们都不会写到数据库中。 SQL服务器中的数据格式为日期时间。
从表单加载方法我设置初始日期值是这样的。
// 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，它会成功保存到数据库中。我做了 google 这个问题并找到了建议我已经在做的事情的解决方案。
默认值在屏幕上看起来不错，而且如果我今天实际选择，似乎也不会改变。
有什么不同的想法吗？
谢谢 大卫
更新
我使用默认日期执行保存并使用名为 SQL Profile Express 的工具从服务器捕获生成的 sql。
执行了三个命令。
执行sp_resetConnection
执行sp_executesql插入
执行sp_executesql更新
我不确定它为什么要进行更新。它似乎在尝试更新现有的不相关记录，而我正在插入一条新记录。 主键字段 QuoteID 是一个标识字段。

然后我又做了几乎相同的事情，但这次在日期时间选择器中设置日期，而不是将它们保留在我的默认日期。 我选择明天（2017 年 5 月 19 日）作为输入日期，2017 年 5 月 26 日作为回拨日期。这次除了 Date Entered 之外的所有字段都被插入到数据库中。
这样就清楚了。这次 CallBackDate 有效，而 Dated Entered 没有。

go
更新 2
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。我正在创建一个新记录，其中 ID 为 2122 左右，更新的记录为 ID 19。果然，如果我查看 ID 为 19 的记录，我会看到非常旧的数据 ~ 2006 年已更新为我的 2017 年日期。 visual studio 到底是怎么想到这个 SQL 的？
更奇怪的是，它看起来总是更新记录 ID 19，这是 table 中的第一条记录。
据我所知：
- 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，但我假设您为 @DateEntered 设置参数的位置不正确。
我不敢相信这竟然如此简单。
我的 FormMainLoad 看起来像这样。
1) 填充我的数据集（第一条记录加载为当前记录）
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。
宾果游戏：顺序错误
当我保存时，它会更新第一条记录并插入新记录。
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();
}
所以我把命令的顺序改成了这样
1) 加载数据集
2) 设置对话框开始新记录
3) 设置默认日期
并且有效。有趣的是，我如何假设问题出在日期时间选择器上让我开始了疯狂的追逐。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);
}
感谢所有发表评论的人。 回答您的问题迫使我更加认真地审视我的代码，并逐步更慢地深入了解代码，直到答案让我眼前一亮。
