title: SQLAlchemy error - "Please configure one or more attributes for these same-named columns explicitly."
body: <p>I am brand new to sqlalchemy. Trying to get a query to work and am having issues with a join.</p>
  
  <p>I have two tables both of which have a column named "Id" and I need to join on that table. My code looks like this:</p>
  
  <pre><code>table1 = server.tab1
  table2 = server.tab2
  joined = server.join(table1,table2, table1.Id == table2.Id)
  where = table1.createDate &gt; start
  results = joined.filter(where).all()
  </code></pre>
  
  <p>This results in the following error message:</p>
  
  <blockquote>
    <p>Implicitly combining column  table1.Id  with column  table2.Id  under attribute 'Id'. Please configure one or more attributes for these same-named columns explicitly.</p>
  </blockquote>
  
  <p>Question is, how do I configure these attributes?</p>
  
  <p>TIA!</p>
