I was told in L2S, the code for update and insert are the same,

db.InsertOnSubmit(row); 
db.SubmitChanges();

and L2S will check to see if it is a insert or update and act approprately in the background.

Is that true?

How about L2E? I tested, looks like in L2E it is not like that. Maybe I did something wrong.
