The RENAME TO clause can be used to change the name of the
    outline. The new name must not already exist in the database.

    If RENAME TO is used in a multischema database, attached with
    MULTISCHEMA IS ON, then only the multischema name is modified
    not the STORED NAME of the object. To change the STORED NAME of
    the query outline you must attach to the database explicitly with
    the MULTISCHEMA IS OFF clause (see the example below). Please
    note that the STORED NAME for the query outline may have been
    generated by Oracle Rdb.

                                   NOTE

       Any queries using the OPTIMIZE USING clause will also need
       to be changed to reference this new outline name.
