Teradata provides only basic ordering functionality for a newly created one-dimensional or multidimensional ARRAY/VARRAY type. This ordering functionality is provided to avoid hashing issues and to permit ARRAY/VARRAY types to be valid for columns in SET tables. The basic ordering functional that Teradata provides does not permit relational comparison of ARRAY/VARRAY values in any form.
