After you run schema comparison, the Schema Comparison document opens, enabling you to include the objects in or exclude them from synchronization.
Note
The changes during the schema synchronization operation are applied only to the target database. The source database remains unchanged.
By default, all objects are selected for deployment.

You can include or exclude all objects, specific objects, or all objects within a section.
Note
By default, objects in the Schema Comparison grid are grouped by status. To change how comparison results are displayed, see Group comparison results.
To include a specific object, select the checkbox for this object.
To include all objects, select the checkbox at the top of the grid.

To include all objects within a specific section, select the checkbox for this section.

To exclude a specific object, clear the checkbox for this object.
