    In PHP versions before 5.0.0 you must use <span class="function"><a href="function.ocicolumnsize.html" class="function">ocicolumnsize()</a></span> instead.
    This name still can be used, it was left as alias of
    <span class="function"><strong>oci_field_size()</strong></span> for downwards compatability.
    This, however, is deprecated and not recommended.
