New DBMS provides virtual columns that are generated based on another
column value in the row, these fields are read-only from DBMS prospective,
so they shouldn’t be included in insert or update statements.

My suggestion is to add **read-only** flag to the BaseField class and if
the flag is true, it shall be skipped from insert/update and can be
selected as usual.

I can do it, if the community will accept it.

Comment:

Thanks for this ticket.
[https://code.djangoproject.com/ticket/31300#comment:1 Generated/Function-
based virtual columns] are a big topic. I don't think it's worth adding
partial support and force users to maintain them manually.

Duplicate of #31300.
