Unable to add column comment on a View. Any way to update comments on multiple columns in bulk?

[prasad_vaze]

I noticed that unlike "Alter Table" there is no "Alter View"  command to add comment on a column in the existing view. This is a regular view created on Tables (and not Materialized view).  

If the underlying table column has comment then the View inherits it but I want to update that only on View column. I am owner of the tables and View. Has anyone solved this or is this a gap in functionality or bug?

Alternatively ,Is there a way to mass apply or upload column comment on multiple columns across Tables or Views? I have a spreadsheet with column descriptions and want to mass apply /upload in Unity catalog instead of "Alter Table" command for each column

Thanks, @Retired_mod for the detailed reply.  Similar to "Alter Table <name> Alter column <name > comment '<>' "  option will there be an option for Views in the future? This will be handy as compared to recreating the Views.

We are currently SQL script to mass-apply ALTER statements. I was hoping any alternative such as excel import/export way

Comment On doesn't work with views.
