Example: UDT Expression Method - Analytics Database - Teradata Vantage

Consider the following statement that creates a structured UDT named address :

CREATE TYPE address
AS (street VARCHAR(20)
   ,zip CHAR(5))
NOT FINAL;

The following statement creates a table that defines an address column named location :

CREATE TABLE european_sales
  (region INTEGER
  ,location address
  ,sales DECIMAL(8,2));

The following statement invokes the zip observer method to retrieve the value of each zip attribute in the location column:

SELECT location.zip() FROM european_sales;
