4.7.5 Transforms for user-defined types

Transforms are SQL-invoked functions that are automatically invoked when values of user-defined types are
transferred from SQL-environment to host languages or vice-versa.

A transform is associated with a user-defined type. A transform identifies a list of transform groups of up to
two SQL-invoked functions, called the transform functions, each identified by a group name. The group name
of a transform group is an <identifier> such that no two transform groups for a transform have the same group
name. The two transform functions are:
- from-sql function : This SQL-invoked function maps the user-defined type value into a value of an SQL
pre-defined type, and gets invoked whenever a user-defined type value is passed to a host language
program or an external routine.
- to-sql function : This SQL-invoked function maps a value of an SQL predefined type to a value of a
user-defined type and gets invoked whenever a user-defined type value is supplied by a host language
program or an external routine.
