For purposes of structured UDTs, assignment operations are defined to be insert, update, and parameter passing SQL operations only.

A structured UDT value can only be assigned by default with a source of the same type. To support assigning a different data type to a structured UDT target, you must create a cast that can be invoked implicitly on assignments from the desired type to the structured UDT (see CREATE CAST and REPLACE CAST).
