while 里的数据为什么不循环呢？ //
生成语句如下：
但在mysqlfront里执行正常，而使用mysql_num_rows()计算也是一条。
SELECT count(*) FROM Realtime_photo WHERE Photo_id = 'ap200301010006 ' or Photo_id = 'ap200301010007 ' or Photo_id = 'ap200301010008 ' or Photo_id = 'ap200301010009 ' or Photo_id = 'ap200301010010 ' or Photo_id = 'ap200301010011 ' or Photo_id = 'ap200301010012'

我使用了同事的库，但感觉是库的问题。库如下
class MYDB
{
var $host; //连接数据库主机名
var $user; //连接数据库用户名
var $passWord; //连接数据库密码
var $selectDataBase; // 选择数据库
var $query; //执行sql
var $nums; //返回行数
var $fetch; //返回结果集
function connection($host,$user,$passWord)
{
$this->;host=$host;
$this->;user=$user;
$this->;passWord=$passWord;
$conn=@mysql_pconnect($this->;host,$this->;user,$this->;passWord) or
die("数据库连接有误,请与管理员联系";
return $conn;
}
function selectDB($db)
{
$this->;selectDataBase=@mysql_select_db($db);
if(!$this->;selectDataBase)
{
echo "请选择数据库";
}
return $this->;selectDataBase;
}
function execute($sql)
{
$this->;query=@mysql_query($sql) or die("SQL执行错误";
return $this->;query;
}
function nums($result)
{
$this->;nums=mysql_num_rows($result);
if($this->;nums<=0)
{
return 0;
}
else
{
return $this->;nums;
}
}
function fetch($result)
{
$this->;fetch = @mysql_fetch_array($result);
return $this->;fetch;
}
