    This function <emphasis>does not</emphasis> return number of rows selected!
    For SELECT statements this function will return the number of rows, that were
    fetched to the buffer with <function>oci_fetch*</function> functions.

  <note>
   <para>
    In PHP versions before 5.0.0 you must use <function>ocirowcount</function> instead.
    This name still can be used, it was left as alias of
    <function>oci_num_rows</function> for downwards compatability.
    This, however, is deprecated and not recommended.
