ASP.NET - VB.NET - SQL Server Express 2012 - Dates de stockage

Question

J'essaie d'obtenir la date sélectionnée à partir du contrôle de calendrier et de l'enregistrer dans une colonne de la base de données.

Je reçois l'erreur suivante:

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

Date de naissance colonne DB:

MISE À JOUR: Ajout d'un nouveau message d'erreur, que je fixe le RegistrationDate et date de naissance. Maintenant, je reçois un nouveau message d'erreur:

The statement has been terminated. 

Toute aide est appréciée!

Answer 1

Quelle valeur avez-vous lorsque vous l'attribuez au paramètre @p9 ??

Ou pourrait RegistrationDate être le coupable? Quelle valeur cette variable a-t-elle lorsque vous l'affectez au paramètre @p18?

Cette erreur se produirait généralement si vous avez une colonne DATETIME dans SQL Server et que vous essayez d'insérer NULL à partir d'une application .NET en elle - qui est converti en 01/01/0001 qui est en dehors de la plage de valeurs de DATETIME.

donc ma recommandation: utiliser DATE (si vous avez besoin que la date - pas de temps) ou DATETIME2 (pour la date et l'heure) dans SQL Server 2008 et plus récent (DATETIME2 ne pas ont ces restrictions de plage de valeurs que DATETIME a)

..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.

Je recommande d'utiliser:

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

au lieu de registerSQL.Parameters.AddWithValue("@p9", DOB)

assurez-vous que DOB n'est pas DateTime.MinValue ou DateTime.MaxValue
