A structured UDT can have more than one constructor method, each of which provides a different initialization option. Constructors have the same method name; however, their parameter lists are different, meaning that their method signatures are different.
The following is an example of a constructor method for the structured type address:
CREATE TYPE address ... CONSTRUCTOR METHOD address(VARCHAR(20), CHARACTER(5) ) RETURNS address SELF AS RESULT LANGUAGE C DETERMINISTIC
This constructor method takes two character strings as input and uses them to initialize the attributes of the address structured type.
You can invoke constructor methods using the NEW syntax (see NEW Syntax for details).
The following bullets briefly summarize how to invoke a constructor method:
- NEW syntax:
NEW structuredTypeName( ... )
- NEW example:
NEW address('10795 Via Del Campo', '92127')
