Solutions

1. A native query cannot be unwrapped/converted to a java.sql.Statement.
2. Use session.doWork() or the JDBC connection directly for Statement-level access.

When it happens

Trigger: An API operation is invoked on a query object that does not support it.

Common situations: Calling query hint, locking, pagination, conversion, or mutation APIs on a query kind (native vs HQL, select vs mutation) that does not implement them.
