Re: Table symbolic link

I did not even think about a table view. I use them very rarely. I also don’t do update, insert or delete on the view I have.

Thanks a lot. That was really helpful.

As others mentioned, you can create a view. But depending on they types of updates you do, other views that already exist on that table, triggers, and the version of PostgreSQL among other issues it may not be a viable option.
