    This seems you are doing some tests or something similar.
    Just the little advice: RTFM! If you don't like documentation reading try another job. I think this forum is for solving of real problems not for step by step knowledge building for newbies.

    yes.

    Oracle will let you add a table without a primary key. But why would you want to.
