Solutions

1. Use xmltable only on supported entity/embeddable mappings on HANA.

When it happens

Trigger: Triggered when the application calls a Hibernate dialect feature that the configured database dialect cannot provide: Unsupported model part container (HANA xmltable).

Common situations: Common when running against a database whose dialect lacks this capability, when a mapping or HQL/Criteria query requests unsupported functionality, or when the wrong dialect is configured for the database in use. Error: Unsupported model part container (HANA xmltable).
