  <para>
   Use <function>db2_fetch_row</function> to iterate through a result set, or
   to point to a specific row in a result set if you requested a scrollable
   cursor.
  </para>
  <para>
   To retrieve individual fields from the result set, call the
   <function>db2_result</function> function.
  </para>
  <para>
   Rather than calling <function>db2_fetch_row</function> and
   <function>db2_result</function>, most applications will call one of
   <function>db2_fetch_assoc</function>, <function>db2_fetch_both</function>,
   or <function>db2_fetch_array</function> to advance the result set pointer
   and return a complete row as an array.
