Правильно ли введен мой код?

Question

Правильно ли введен мой код. Я пытаюсь выбрать из моей базы данных набор чисел. Вот код:

mysql_connect(db_server, db_user, db_pass); 
$result = mysql_db_query(db_name,"SELECT *, COUNT(track.usr_id) AS usr_views FROM user, track WHERE track.usr_id = $usr_id AND track.timesin = $les_tag GROUP BY $usr_id ORDER BY usr_views LIMIT 1");  
$usercheck = mysql_result($res, 0, 0); 
$Userstats = $usercheck; 

Я выбираю код неправильно?

Answer 1

Попробуйте это ...

$conn = mysql_connect(db_server, db_user, db_pass); 
if ($conn !== false) { 
    mysql_select_db(db_name); 
    $result = mysql_query("SELECT *, COUNT(track.usr_id) AS usr_views FROM user, track WHERE track.usr_id =  $usr_id AND track.timesin = $les_tag GROUP BY $usr_id ORDER BY usr_views LIMIT 1");  
    if ($result !== false && mysql_num_rows($result) > 0) { 
     $usercheck = mysql_fetch_row($result); 
     $Userstats = $usercheck; 
    } 
} else { 
    die("There was an error while connecting to the mysql server"); 
}
