and
(cons 'a '(b.c)) ;; (A B.C)
I need to create the following list ((a.b).c) using cons so i'm trying to understand what that "." represents.
L.E. : I have the following (cons (cons '...

If you enter (FOO.BAR) then Lisp will read it as a list with one symbol as its contents... .
If you enter FOO.BAR, then Lisp will read it as one symbol .
B.c is a symbol with a name of three characters: b, ., and c .
Between two characters is a part of a symbol.

What's your choice and reason?

Your code block should work, however the manual recommends to run... .
Mysql_error() will always throw an error if the insert operation fails, so fetching the insert_id is not really necessary as far as I can see, unless you need it for further processing .

What do you think?
If you've done time any time in your life and were paroled - wether that parole was yesterday or 29 years ago are you always an ex-con?

Will a con be a con for life?
In the eyes of Society = yes
In Legally terms = yes
My views aren't.

What exactly is the definition of a Common Lisp Cons Cell? How is a Cons Cell different than a standard linked list item? After all, both the cons cell and the linked list item have a value and a pointer to the next cell or item... or is this understanding...

A cons cell is closer to a binary tree....
General usage of course is to point to a "value" with the left one, and to another Cons cell (or nil) with the "right" one.
Cons cells in general hold two pointers that can point to anything.

Cons2 (cons 3 null) =....
cons 3 null => (3) 3.
Null => () --read as empty list 2.
A list is made up of an item cons a list
So these are lists:
1.
The null list (empty list) is a list 2.
The definition of a list is recursive.
