title: Oracle OCCI - get column by name instead of index
body: <p>Using oracle OCCI is it possible instead of supplying an index for the column when requesting data from a query resultset, to actually pass the column name and get the data?</p>
  
  <p>So instead of doing: (pseudocode)</p>
  
  <pre><code>std::string query = "SELECT NAME FROM CUSTOMERS;";
  
  std::string myresult = oracle.getString(1); // name column in query
  </code></pre>
  
  <p>you'd do this:</p>
  
  <pre><code>std::string myresult = oracle.getString("NAME"); //column name to get string from
  </code></pre>
  
  <p>is there any way to do this?  I have looked around, but been unable to find anything, besides perhaps going to fetch the table's metadata.</p>
