Remarks

The DbTypeAttribute can be used to designate a provider-specific database type for the column which the persistent property or field is mapped to:

C#

public class MyPersistentObject : XPObject {
    // ...
    DateTime myReadDate;
    [DbType("smalldatetime")]
    public DateTime ReadDate {
        get { return myReadDate; }
        set {
                myReadDate = value;
        }
    }
}

VB.NET

Public Class MyPersistentObject
   Inherits XPObject
   ' ...
   Private myReadDate As DateTime
   <DbType("smalldatetime")>  _
   Public Property ReadDate() As DateTime
      Get
         Return myReadDate
      End Get
      Set
            myReadDate = value
      End Set
   End Property
End Class
