把adodb里面的adodb-oci8.inc.php中SelectLimit函数其中一部分替换成下面代码，就可以使用SelectLimit了
[php]if ($offset < $this->selectOffsetAlg1) {
if ($nrows > 0) {
if ($offset > 0) $nrows += $offset;
//$inputarr['adodb_rownum'] = $nrows;
if ($this->databaseType == 'oci8po') {
$sql = "select * from (".$sql.") where rownum <= ?";
} else {
$sql = "select * from (select rownum as numrow, c.* from (".$sql.") c ) where numrow > $offset and numrow <= $nrows";
}
$inputarr['adodb_offset'] = $nrows;
$nrows = -1;
}
// note that $nrows = 0 still has to work ==> no rows returned

$rs =& ADOConnection::SelectLimit($sql,$nrows,$offset,$inputarr,$secs2cache);
return $rs;[/php]
