Teradata Database provides system functions, operators, and expressions that operate on either 1-D, n-D, or both ARRAY data types. These functions allow you to perform arithmetic, relational, and aggregate operations on an array in its entirety or on a subset of the elements composing the array. For information about these functions, see “ARRAY Functions and Operators” in Teradata Vantage™ - SQL Functions, Expressions, and Predicates, B035-1145.
