title: How to code for SELECT * with SOCI?
body: <p>In most examples for <a href="http://soci.sourceforge.net/" rel="nofollow">SOCI</a>, the caller must know the fields and types in a query and specifies them through a <code>soci::rowset&lt;&gt;</code> of <code>boost::tuple&lt;&gt;</code> or through some other means.</p>
  
  <p>Is there a way to code <strong>without</strong> knowing the types and number of columns beforehand, as in a <code>SELECT * FROM ...</code> query?</p>
  
  <p>If so, could you post a short example?</p>
