Is it possible to write an entity for a view without an id field?

Question

Java

Good mood.
There was such a problem: there is a ready-made base, which I cannot change with all my desire. This database has already created a view that does not have an id field. All I need is just reading and displaying at a given interval.
How can I properly describe an entity? I wanted to do it by timestamp - but I noticed records with the same timestamp :(

You can try with a composite key:
