New object-relational features for Oracle 10g release 1 (10.1) include the following collection enhancements:
New functionality for nested table and varray storage, including the evolution of varray size and specification of a tablespace when storing nested tables. See "Collection Data Types".
New functionality for nested table comparisons and ANSI SQL multiset operations for nested tables. See "Operations on Collection Data Types".
