title: JDBC ResultSet get columns with table alias
body: <p>Imagine I have a query like </p>
  
  <pre><code>SELECT * from table1 a, table2 b where (WHATEVER)
  </code></pre>
  
  <p>Maybe both tables have the same column name. So I though it would be nice to access the data via</p>
  
  <pre><code>resultSet.getString("a.columnName");
  resultSet.getString("b.columnName");
  </code></pre>
  
  <p>But this backfires on me and I get nothing. I read the API, but they don't really talk about this case. Is such a feature vendor dependent?</p>
