ca.uhn.fhir.jpa.migrate.taskdef.DropPrimaryKeyTask

public class DropPrimaryKeyTask
extends BaseTableTask

Migration task that handles cross-database logic for dropping a primary key.

The process involves 2 steps for most databases:

1. Running SQL to introspect the metadata tables to determine the name of the primary key.
2. Running an ALTER TABLE to drop the constraint found above by name.
