count_all () or count_all_results ()?

[eluser]domix24[/eluser]
hello,
I type this in the url (localhost/codeigniter/registration/registration/) I see well the form I type words in the corresponding fields (username = domix24 pass = ******** pass2 = ******** [email protected]) (these fields of are not in the database) I confirm the form and I see these figures: 00 wants to means(false for the email and false for the username). If I put count_all () for 2, it shows me 11 well, but if I test data which are in the database (username = domix24 and email = [email protected]) (I vien to enter them with the script) I also obtain 11 and it reinsert in the database. You have an idea of which to put between count_all () (just insertions in the database) and count_all_result () (no insertion in the database)?
thank you.
