ASP.NET - VB.NET - SQL Server Express 2012 - 存储日期

Question

我试图从日历控件中获取所选日期并将其存储到数据库中的列。

，我发现了以下错误：

SqlDateTime overflow. Must be between 1/1/1753 12:00:00 AM and 12/31/9999 11:59:59 PM.

出生DB列日期：

UPDATE：增加了新的错误消息，因为我固定RegistrationDate和DOB。现在我收到一条新的错误信息：

String or binary data would be truncated. 
The statement has been terminated. 

任何帮助表示赞赏！

Answer 1

什么值确定DOB当您将其分配给参数@p9？

或可能RegistrationDate是罪魁祸首？什么价值做这个变量时，你将它分配给参数@p18 ??

，如果你有在SQL Server DATETIME列，你想从.NET应用程序到其插入NULL通常会出现此错误 - 这被转换为01/01/0001这是DATETIME值范围之外。

因此我的建议： - 或DATETIME2（两个日期和时间），在SQL Server 2008和更高（DATETIME2不不有这些值的范围限制为DATETIME（没有时间，如果你只需要日期）使用DATE有）

Answer 2

这可能是一些使用

esp.the第二点的隐式数据转换导致数据错误

..You can accidentally introduce data errors if you use the Parameters.AddWithValue syntax to send a date datatype to your database, then you are at the mercy of the database to identify how it will store your date value. This can lead to problems since there are numerous ways of entering dates: mm/dd/yyyy in North America, dd/mm/yyyy in the UK, and yyyy-mm-dd as an upcoming standard. The database will look at the date value of 1/2/2012 that you are sending and can handle the ’1′ as either the day or as the month.

我会建议使用：

registerSQL.Parameters.Add("@p9", SqlDbType.DateTime).Value = DOB.Date 

，而不是registerSQL.Parameters.AddWithValue("@p9", DOB)

确保DOB不是DateTime.MinValue或DateTime.MaxValue
