title: Three Tables with same Worksheet
body: <p>I have three tables with the same work sheet like this</p>
  
  <pre><code>[ id  -  title  -  context ]
  </code></pre>
  
  <p>i'm trying to make a relation between them like this</p>
  
  <pre><code>$query = "SELECT db.title, db.context FROM table1 db, table2 db, table3 db WHERE id = :id";
  </code></pre>
  
  <p>but i keep getting this error</p>
  
  <pre><code>Not unique table/alias: 'db'
  </code></pre>
  
  <p>is there a way to relate between all the tables with same alias?</p>
