You may refer to the [UPDATE Statement](https://community.denodo.com/docs/html/browse/7.0/vdp/vql/inserts_updates_and_deletes_over_views/update_statement/update_statement) section of the Virtual DataPort VQL Guide to understand the syntax on executing an UPDATE statement.
However, note that there are conditions that needs to be met before a view can be updated. For example, a derived view is not updateable if its underlying view is not updateable.
You may find these conditions under the [Inserts, Updates and Deletes Over Views](https://community.denodo.com/docs/html/browse/7.0/vdp/vql/inserts_updates_and_deletes_over_views/inserts_updates_and_deletes_over_views#inserts-updates-and-deletes-over-views) section of the Virtual DataPort VQL Guide too.
Hope this helps!
