This example first creates a structured UDT named employee and then creates ARRAY types based on it using both Teradata-style and Oracle-style syntax.

     CREATE TYPE employee AS (
       first_name  CHARACTER(10),
       last_name   CHARACTER(10),
       employee_id INTEGER)
       …;

The first example creates the ARRAY type structudt_ary , which is based on employee, using Teradata-style syntax.

     CREATE TYPE structudt_ary AS 
     employee ARRAY[20];

The next example creates the same ARRAY type as a VARRAY type using Oracle-style syntax.

     CREATE TYPE structudt_ary AS 
     VARRAY(20) OF employee;
