Regardless of the table type, doesn't matter - Active Record methods will automatically do what you tell them to - or at least try to.
Code:
// This will immediately attempt to insert a row and return TRUE/FALSE based on success
$this->db->insert('users', array('email'=>$email));
Quote:If I do an insert, Active Record commit the transation automatically in a innodb table
If you do an insert, there is no transaction. Transactions only occur when you explicitly request them.
Quote:I can do an insert without transations with an innondb table?
Yes - you can do it with any table type.
