This example creates a structured UDT named person from four predefined data types and the structured UDT address, making it a 2-level nested type. The UDT is nested because the type address is a structured UDT having two attributes. In this case, both of those attributes are predefined types, but if one or more of them had been a structured type, person would be a 3-level nested type.

    CREATE TYPE SYSUDTLIB.person AS (
       ssn         CHARACTER(11), 
       first_name  VARCHAR(20),
       middle_name VARCHAR(20),
       last_name   VARCHAR(20),
       domicile    address ) 
    NOT FINAL;
