Return table name in FROM with regex query

I am using a request like SELECT * FROM /city1_\d{1,2}/ LIMIT 1. However, since I am using an ORM to deserialize the request, I have no easy way of knowing the result of the regex.

Is there a way like SELECT seriesName, * FROM /city1_\d{1,2}/ LIMIT 1 where I can also get the series name, for knowing what the Regex equated to?
