    Arrow Unanswered: SQL subselect

    Hi all,

    The fields of TABLE are: city, high, and, low.

    I would like to get all pairs of cities,
    that the temp range of the first city in the
    pair fully contains the range of the second city in
    the pair.

    here is the data:

    city high low
    NYC 60 40
    Moscow 80 20
    Tokyo 55 50

    The results will be:
    Moscow NYC
    Moscow Tokyo
    NYC Tokyo
