Members

MemberDescription
None A property marked with this flag is always persisted. It does not matter if the persistent is inserted or updated in the storage. This is the default behaviour of a property.
DontInsert A property marked with this flag is not inserted. If the persistent object is updated this property is also updated.
DontUpdate A property marked with this flag is not updated. If the persistent object is inserted this property is also inserted.

Example

The following example shows a property that is only saved during an insert of the persistent object. The FieldAttribute is used to connect a property with a field of the entity. For additional information check out the documentation of the FieldAttribute or the PersistentAttribute.
C#Copy Code
            [Persistent("USER")] 
public class User 
{ 
    private string _name = null; 
     
    [Field("NAME", PersistBehaviours = PersistBehaviours.DontUpdate)] 
    public string Name 
    { 
        get { return _name; } 
        set { _name = value; } 
    } 
     
    // ... Other properties and fields. 
} 
    

Remarks

This enumeration is used to mark properties with special persisting behaviour. It allows to control the persisting behaviour on properties during insert and update operations of the persistent object. DontInsert means, for example, that the value of the property is not inserted during an insert operation of the persistent object.
