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

Question

What is the difference between: .Save();
.Add(); .Update():

Answer 1

You don't mention which templates you're using (I'm going to assume ActiveRecord), but as a general rule:

• Save will insert if the object IsNew==true or otherwise it will update.
• Add will always insert a new record.
• Update will only update an object with IsNew==false and will fail if there is no corresponding record in the db for the instance.
