If you are mentioning to alter these Metadata elements in Denodo, I could do with three ways that are at creation via introspection, manually through the gui, or programmatically through VQL.
Since you have all the needed information to modify the columns of view for **ALTER TABLE** VQL command, I recommend that you should create a script to output the appropriate VQL like below example, and run via import or in the VQL Shell.
`ALTER TABLE internet_inc (
ALTER COLUMN incidence_id MODIFY decimal FALSE
The document [Modifying a Base View](https://community.denodo.com/docs/html/browse/latest/en/vdp/vql/creating_a_base_view/modifying_a_base_view/modifying_a_base_view) describes the syntax of the statement **ALTER TABLE**. I would use this document as a good reference.
Hope this helps!
