  • RENAME TO clause to rename the continuous aggregate view;
  • SET SCHEMA clause to set the new schema for the continuous aggregate view;
  • SET TABLESPACE clause to move the materialization of the continuous aggregate view to the new tablespace;
  • OWNER TO clause to set new owner for the continuous aggregate view.
