As mentioned in the limitations of [**Denodo Hibernate Dialect - User Manual**](https://community.denodo.com/docs/html/document/denodoconnects/8.0/Denodo%20Hibernate%20Dialect%20-%20User%20Manual#h.azkv3fjcdjx8), the Denodo Hibernate Dialect does not support DDL operations.
If I come across this error, I would set the log level as **DEBUG** in my client application for debugging the issue which is causing the error.
Also, you could debug the issue by **[Setting the log level](https://community.denodo.com/docs/html/browse/8.0/vdp/vql/stored_procedures/predefined_stored_procedures/logcontroller#logcontroller)** in Virtual DataPort to DEBUG/TRACE and check the log files located under the directory "**<DENODO_HOME>\logs\vdp**". Depending on the ORM framework you are using, you can try using an alternative to Hibernate.
If the issue persists and you are a user with valid support access, you can open a Support case in **[Denodo Support Site](https://support.denodo.com/)** and our Support Team will help you.
Hope this helps!
