title: Retrieving data type information for columns in an Oracle OCCI ResultSet
body: <p>After sending a simple query via OCCI (example: select * from ALL_USERS) I'm in the need to know the datatype for the column, for the moment I've been playing with the     <strong>ResultSet::getColumnListMetaData()</strong> method without success.<br>
  Questions:<br>
   1. How can I get the datatype by using the aforementioned method and the MetaData class?<br>
   2. Is there any better documentation out there than the one already provided by oracle?</p>
