I am intrigued by the rollback capability that allows you to reference the changeset that originally created a statement:
<changeSet id="changeRollback2-drop" author="liquibase">
<dropTable tableName="changeRollback2"/>
<rollback changeSetId="changeRollback2-create" changeSetAuthor="liquibase"/>
</changeSet>
How can we do this using the SQL Dialect?
