Here's how to do something similar in Q (KDB)

    ([]x?x:1000000)
Which gives a table of a million rows like:

    x
    ------
    877095
    265141
    935540
    49015
    ...

Nothing to do with the article, SQL, or a DB, but I can't help wanting to add even just a bit when I see array languaes mentioned. So, in J it's just:

    ?~1000000
or, if you don't need elements to be unique:

    ?$~1000000
Though it's just an array, not a persistent table - I don't know much about Jd :(

An R vector would be `1:1000000`
