Administer User-Defined Types
User-Defined types (UDTs) allow users to create custom data types that model the structure and behavior of data in their applications. UDTs can augment the Teradata Database with data types having capabilities not offered by Teradata predefined (built-in) data types. UDTs are defined with the CREATE TYPE statement.
Teradata Database supports three types of UDTs: distinct, structured, and array.
For more information, see “Additional Information on UDTs and UDFs” on page 78.
