    DB_DataObject calculates the sequence key(s) by taking the first key returned by the keys() function.
    In this case, the keys() function returns user_id as the first key. user_id is not a sequence, but
    DB_DataObject's sequenceKey() will incorrectly think it is. Then, since the sequenceKey() is a numeric
    type, but is not set to autoincrement in the database, DB_DataObject will create a _seq table and
    manage the sequence itself. This is not the correct behavior for the user_id in this class.
    So we override that incorrect behavior, and simply say there is no sequence key.
