    How to modify an existing table constraint

    Hai All,
    It's possible to modify an existing table constraint -
    ----for example, to add "ON DELETE CASCADE" to an existing foreign key
    constraint?


    With regards

    Hi.

    The syntax diagram for 9i does not give an option to modify this clause of a ref constraint. Looks like you have to drop and recreate it.

    See: http://download-west.oracle.com/docs...2a.htm#2081099

    Cheers
