There is a "primary key" which is not the main order to access rows.

What I am emulating is a large memory space and the "primary key" is just
used not to duplicate rows.

Please re-read my post as well as the very manual reference you later gave; the PRIMARY KEY _is_ the row number, if you have one. If you use auto_increment for your primary key, then ORDER BY {primary key} _is_ ordering by insert order. If you want your query to use any other order, you _must_ create a column for that purpose; the database subsystem has no way of knowing (nor should it bother to track) what order rows are inserted / stored in.
