You don't need to insert id, insert rest of the details.

It would be easier to advise if we knew what you had already tried. But the general idea is to leave the book-id column out of your INSERT statement and let the database generate the key value.

so for me to understand a simple example:

insert into books(every field exept book_id) values(every value exept book_id)

is this right??

Yes, that is correct. The database takes care of the one field you left out.
