错误“警告:mysql_result()[function.mysql-result]:无法跳转到第0行”

This is my error:

Warning: mysql_result() [function.mysql-result]: Unable to jump to row 0 on MySQL result index 53 in C:\xampp\htdocs\includes\class.rooms.php on line 35

This is the line in the coding:

return mysql_result(
       dbquery(
           "SELECT " . $var . " FROM rooms WHERE id = '" . $roomId . "' LIMIT 1"
       ), 0);

    Firstly, function dbquery is unfamiliar to me. I know mysql_query, but maybe it's your own method. The problem is, most possibly, that your query returns no rows. Try debugging with

    $result = ..query..
    if (!mysql_num_rows($result))
        echo "No rows.";
