    Description copied from interface: ResultSet
    
    Needs to be called before the result set will do anything. Need to call before getNextRow(), or for a result set that doesn't return rows, this is the call that will cause all the work to be done.

    Description copied from interface: ResultSet
    
    Tells the system that there will be no more access to any database information via this result set; in particular, no more calls to open(). Will close the result set if it is not already closed.
