Subsonic 3.Save () VS.Update () and .Add ()

Question

What is the difference between: .save ();
.Add (); .update ():

Answer 1

You do not specify which templates you use (I'm going to use ActiveRecord), but as a rule:

• Save will be inserted if the object IsNew==trueor otherwise it will be an update.
• Add will always insert a new record.
• The update will only update the object with IsNew==falseand will not work if there is no corresponding entry in db for the instance.
