title: Join 10 tables on a single join id called session_id that's stored in session table. Is this good/bad practice?
body: <p>There's 10 tables all with a session_id column and a single session table.   The goal is to join them all on the session table. I get the feeling that this is a major code smell. Is this good/bad practice ?<br>
  What problems could occur?</p>
