The Structural Compare view in the compare editor shows the structural
differences between data objects. You can use this view to merge structural
changes from one object to another. This view is available only when you perform
a comparison among data objects.
The following basic comparison actions are available in the Structural
Compare view of the compare editor when you compare data objects:
- Copy from Left to Right

- Copies the structural attributes of the object on the left side of the
editor to the object on the right side of the editor.
- Copy from Right to Left

- Copies the structural attributes of the object on the right side of the
editor to the object on the left side of the editor.
If you make changes to a model object, the changes
are automatically added to the model; then you must save the model to save
the changes. You can also choose not to save the changes, and generate delta
DDL statements instead.
If you make changes to a server object, then
you must generate delta DDL statements for the object and then deploy it to
the server to save the changes.
