ORDER BY DESC LIMIT 数据库包含超过 1000 个条目

Question

一切正常，然后我一直得到 999 作为最后一个值。我假设它看到 9 大于 1 中的 1000。不过我可能错了。但是它不会返回任何超过 1000 的值。代码发布在下面。任何帮助都会很棒。

$db = new PDO('mysql:host='. $host .';dbname='.$db_name, $db_username, $db_password);

$statement = $db->prepare("select * from users where user_name = :user_name");
$statement->execute(array(':user_name' => $user)); //change send to variable
$row = $statement->fetch();

///////////////////////////////////////////////////////////////////////////////////////////////////////////

    $db2 = new PDO('mysql:host='. $host .';dbname='.$db_name_uroll, $db_username, $db_password);

//Remove $db2 prepare
$statement2 = "select * from `{$user}` ORDER BY bet_id DESC LIMIT 23";    

$bid = array();

if ($stmt = $db2->query($statement2)) //PDO::query() returns a PDOStatement on success or false on failure.
{

    //If we got a PDOStatement as a return value from PDO::Query() !!!ECHO WHILE FETCHING!!! 
    while($row2 = $stmt->fetch(PDO::FETCH_ASSOC)) //This loop will keep going for as many rows as the PDOStatement returns.
    {

        $bid[] = $row2['bet_id'] ;

    }
}

SELECT column_name,column_name
FROM table_name
ORDER BY column_name,column_name ASC|DESC;
