Specifies the repository path name of a repository field
    definition. SQL creates the domain using the definition from
    this field and gives the domain the name of the field definition.

    Creating a domain based on a repository domain definition is
    useful when many applications share the same definition. Changes
    to the common definition can be automatically reflected in all
    applications that use it.

    You can create a domain using the FROM path-name clause only if
    the field definition in the repository was originally created
    using the repository CDO utility. For instance, you cannot create
    a domain using the FROM path-name clause if the definition was
    created in the repository as part of an SQL session. Oracle
    Rdb requires that the field names referenced in the VALID IF
    expression of the CDO utility match the name of the global field
    being defined or changed.

                                   NOTE

       Changes by other users or applications to the field
       definition in the repository will affect the domain
       definition once the database is integrated to match the
       repository with an INTEGRATE DATABASE . . . ALTER FILES
       statement.

    You can use the FROM path-name clause only if the database was
    attached specifying PATHNAME. You can specify either a full
    repository path name or a relative repository path name.

    You cannot specify formatting clauses when you use the FROM path-
    name form of the CREATE DOMAIN statement.

    You cannot use the FROM path-name clause when embedding a CREATE
    DOMAIN statement in a CREATE DATABASE statement.
