20.2.6. Incremental Schema Updates

The SchemaUpdate tool will update an existing schema with "incremental" changes. The SchemaUpdate depends upon the JDBC metadata API and, as such, will not work with all JDBC drivers.

You can embed SchemaUpdate in your application:

Configuration cfg = ....;
new SchemaUpdate(cfg).execute(false);

Configuration cfg = ....;
new SchemaUpdate(cfg).execute(false);
