title: How to suppress warnings on cross join select without where clause in sqlalchemy?
body: <p>When doing something like :</p>
  <pre><code>import sqlalchemy as sa
  
  with session() as S:
    print(S.execute(sa.orm.select(A, B)).all())
  </code></pre>
  <p>sqlalchemy display this warning :</p>
  <pre><code>&lt;ipython-input-2-fe928e97d8b6&gt;:1: SAWarning: SELECT statement has a cartesian product between FROM element(s) &quot;A&quot; and FROM element &quot;B&quot;
  </code></pre>
  <p>However... A cartesian product (called cross product elsewhere...) is exactly what I am doing and want to do...</p>
  <p>So how to suppress this warning ?</p>
