Hi,
First, I think it's useful to know that field and view descriptions are accessible via the JDBC driver. There's some more information on this here:
https://community.denodo.com/docs/html/browse/7.0/vdp/developer/access_through_jdbc/details_of_the_jdbc_interface/details_of_the_jdbc_interface#description-of-views-and-their-fields
There are also Denodo stored procedures which allow access to the metadata, including descriptions:
https://community.denodo.com/docs/html/browse/7.0/vdp/vql/stored_procedures/predefined_stored_procedures/predefined_stored_procedures
If you want the descriptions to appear as column headers, however, you will need to update (either manually or via ALTER TABLE statements) the names of the fields.
Hope this helps.
