How to link 2 DB in a view?

I like to show data from the origin DB and a second data from another DB with the same keyword from the first DB in a view, like the @DbLookup in a field. Any help/idea?

Thanks

This is not possible by just making a view.

Consider the use of a folder : search all the documents you need and put them in a folder.
