ASP.NET - VB.NET - SQL Server Express 2012 - 存儲日期

Question

我試圖從日曆控件中獲取所選日期並將其存儲到數據庫中的列。

，我發現了以下錯誤：

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：增加了新的錯誤消息，因爲我固定RegistrationDate和DOB。現在我收到一條新的錯誤信息：

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

任何幫助表示讚賞！

Answer 1

什麼值確定DOB當您將其分配給參數@p9？

或可能RegistrationDate是罪魁禍首？什麼價值做這個變量時，你將它分配給參數@p18 ??

，如果你有在SQL Server DATETIME列，你想從.NET應用程序到其插入NULL通常會出現此錯誤 - 這被轉換爲01/01/0001這是DATETIME值範圍之外。

因此我的建議： - 或DATETIME2（兩個日期和時間），在SQL Server 2008和更高（DATETIME2不不有這些值的範圍限制爲DATETIME（沒有時間，如果你只需要日期）使用DATE有）

Answer 2

這可能是一些使用

esp.the第二點的隱式數據轉換導致數據錯誤

..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.

我會建議使用：

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

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

確保DOB不是DateTime.MinValue或DateTime.MaxValue
