  <para>
   Returns an object containing the next result-set row of a query.
   Each attribute of the object corresponds to a column of the row.
   This function is typically called in a loop until it returns
   &false;, indicating no more rows exist.

  <para>
   Returns an object.  Each attribute of the object corresponds to a
   column of the row.  If there are no more rows in
   the <parameter>statement</parameter> then &false; is returned.
  </para>
  <para>
    Any <literal>LOB</literal> columns are returned as LOB descriptors.
  </para>
  <para>
   <literal>DATE</literal> columns are returned as strings formatted
   to the current date format.  The default format can be changed with
   Oracle environment variables such as <literal>NLS_LANG</literal> or
   by a previously executed <literal>ALTER SESSION SET
   NLS_DATE_FORMAT</literal> command.
  </para>
  <para>
   Oracle's default, non-case sensitive column names will have
   uppercase attribute names.  Case-sensitive column names will have
   attribute names using the exact column case.
   Use <function>var_dump</function> on the result object to verify
   the appropriate case to use for each query.
  </para>
  <para>
    Attribute values will be &null; for any <literal>NULL</literal>
    data fields.
