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";
