php网站首页报错 Resource id #6
测试页面报错：
Error page: /index.php
Error infos: No database selected
Error sql: select * from c_seo where id=1

不知道问题出来哪里，有人帮我看下吗
$this->queryString 的值是select * from c_seo where id=1
$this->linkID 的值是Resource id #6



function Query($id="me",$sql='')
{
	$this->Execute($id,$sql);
}

function Execute($id="me", $sql='')
{
	global $DB;
	if($DB->isClose)
	{
		$this->Open(false);
		$DB->isClose = false;
	}
	if(!empty($sql))
	{
		$this->SetQuery($sql);
	}

	//SQL语句安全检查
	if($this->safeCheck)
	{
		CheckSql($this->queryString);
	}

	$this->result[$id] = mysql_query($this->queryString,$this->linkID);
	if($this->result[$id]===false)
	{
		$this->DisplayError(mysql_error()." 
Error sql: ".$this->queryString."");
	}
}

function DisplayError($msg)
{
	$errorTrackFile = dirname(__FILE__).'/../data/mysql_error_trace.inc';
	if( file_exists(dirname(__FILE__).'/../data/mysql_error_trace.php') )
	{
		@unlink(dirname(__FILE__).'/../data/mysql_error_trace.php');
	}
	$emsg = '';
	$emsg .= "

	$emsg .= "\r\n";
