CREATE TYPE Examples | Teradata Vantage - Example: One-Dimensional ARRAY Type - Teradata Vantage - Analytics Database

These examples all create a one-dimensional ARRAY type named phonenumbers_ary.

The first example uses Teradata-style syntax and initializes all of its elements to nulls.

     CREATE TYPE phonenumbers_ary AS 
     CHARACTER(10) ARRAY[5] 
     DEFAULT NULL;

The next example uses Oracle-style syntax to create an identical VARRAY type to the type created in the first example.

     CREATE TYPE phonenumbers_ary AS
     VARRAY(5) OF CHARACTER(10) 
     DEFAULT NULL;

The final example uses Oracle-style syntax to create an identical VARRAY type, but does not initialize the elements to nulls.

     CREATE TYPE phonenumbers_ary AS 
     VARRAY(5) OF CHARACTER(10);
