word.

<p>
    ALTER
DATABASE&#29992;&#20110;&#26356;&#25913;&#25968;&#25454;&#24211;&#30340;&#20840;&#23616;&#29305;&#24615;&#12290;
</p>
<?
ob_start("ob_iconv_handler");
?>
<p>
    ALTER
DATABASE&#29992;&#20110;&#26356;&#25913;&#25968;&#25454;&#24211;&#30340;&#20840;&#23616;&#29305;&#24615;&#12290;
