The following statement uses the built-in constructor function and mutator methods to return a new instance of the address UDT and insert it into the european_sales table:

INSERT INTO european_sales 
VALUES (101, address().street('210 Stanton').zip('76543'), 500);

Teradata Database executes the UDT expression in the following order:

Step Invocation Result
1 address() constructor function Default UDT instance
2 mutator method for street UDT instance with street attribute set to '210 Stanton'
3 mutator method for zip UDT instance with zip attribute set to '76543'

The final result of the UDT expression is an instance of the address UDT with the street attribute set to '210 Stanton' and the zip attribute set to '76543'.
