【问题描述】：
我将 2 个同步时间作为 2 个新列添加到我的数据库中，并插入如下值：
USE [DB]
ALTER TABLE [dbo].[TableName]
ADD ColumnName2 time, ColumnName3 time
这是为了添加列。
为了插入我所做的行值：
USE DB
INSERT INTO TableName (ColumnName2, ColumnName3)
VALUES ('20:30:00', '23:30:00')
这是那些列的行中固定时间的数据。
我还浏览了应用程序的所有层，例如（控制器、模型、视图、查询、服务、接口等。现在，当我尝试更新任何添加的新时间时，它们默认为第一次已经以 COLUMN 形式存在于表中，并在行中显示时间。
我无法从应用程序中发布时间字段的图像，因为这是不允许的。但是，图像在一个小面板中，由 3 个字段 (textboxfor) 组成，每个字段都有一个时间选择器。
任何帮助将不胜感激。
谢谢
现在我想我会发布一些示例代码，看看是否有帮助

【问题讨论】：
-
如果这会让事情变得更容易，有没有办法在数据库中固定这些时间？
-
如果您压缩标题以建议您尝试纠正的行为，您可能会获得更多浏览量。
-
我很抱歉，我想我试图尽可能地描述性。
