Timestamp on Object Creation
Sometimes, it may be useful to have a timestamp of when a database object is created. This can be done using an abstract class with a constructor that sets the timestamp.
In code, it would look something like this:
[Database]public abstract class BaseOfAllOtherClasses{public DateTime Inserted { get; set; }​public BaseOfAllOtherClasses(){Inserted = DateTime.Now;}}​public class Foo : BaseOfAllOtherClasses {}public class Bar : BaseOfAllOtherClasses {}
From this, it is possible to get when all the instances were created chronologically by using the following query:
SELECT b.Inserted FROM BaseOfAllOtherClasses e ORDER BY e.Inserted
