使用原则查询生成器快速查询

Question

我有以下查询，我想转换为使用原则的查询生成器。

SELECT 
    u.user_id, 
    u.username, 
    u.create_date AS join_date, 
    u.last_login_date, 
    u.membership_level, 
    u.create_date, 
    avg(round((ug.toggle_count/ceil((g.ply_count + 1)/2)) * 100, 1)) AS __avg_toggle_ratio, 
    count(g.game_id) AS __game_count, 
    ugse.rating AS __echess_rating, 
    ugse.total_win_count AS __echess_win_count, 
    ugse.total_loss_count AS __echess_loss_count, 
    ugse.total_draw_count AS __echess_draw_count, 
    (SELECT concat(ugsl.rating,'|',ugsl.total_win_count,'|',ugsl.total_loss_count,'|',ugsl.total_draw_count) FROM user_game_stats_live ugsl WHERE ugsl.user_id = u.user_id AND ugsl.game_time_class = 'lightning') AS __lightning_data, 
    (SELECT concat(ugsl.rating,'|',ugsl.total_win_count,'|',ugsl.total_loss_count,'|',ugsl.total_draw_count) FROM user_game_stats_live ugsl WHERE ugsl.user_id = u.user_id AND ugsl.game_time_class = 'blitz') AS __blitz_data, 
    (SELECT concat(ugsl.rating,'|',ugsl.total_win_count,'|',ugsl.total_loss_count,'|',ugsl.total_draw_count) FROM user_game_stats_live ugsl WHERE ugsl.user_id = u.user_id AND ugsl.game_time_class = 'standard') AS __standard_data, 
    (SELECT uts.rating FROM user_tactics_settings uts WHERE uts.user_id = u.user_id AND uts.attempt_count >= 10) AS __tactics_rating 
FROM 
    game g 
JOIN user_game ug ON g.game_id = ug.game_id 
JOIN user_game_stats_email ugse ON ug.user_id = ugse.user_id 
JOIN user u ON ug.user_id = u.user_id 
WHERE 
    g.last_move_time >= DATE_SUB(NOW(), INTERVAL 5 DAY) AND 
    g.ply_count >= 20 AND 
    u.is_enabled = 1 
GROUP BY 
    ug.user_id 
HAVING 
    __avg_toggle_ratio >= 90 AND 
    __game_count >= 10 
ORDER BY 
    __avg_toggle_ratio DESC 

查询生成器是否能够重写这种查询？我应该使用其他方法吗，如果是的话，怎么样？

我不知道有关查询生成器，但我woyld使用 'createNativeQuery' 的方法：

<?php 
use Doctrine\ORM\Query\ResultSetMapping; 

$rsm = new ResultSetMapping(); 
// build rsm here 

$query = $entityManager->createNativeQuery("SELECT 
                u.user_id, 
                u.username, 
                u.create_date AS join_date, 
                u.last_login_date, 
                u.membership_level, 
                u.create_date, 
                avg(round((ug.toggle_count/ceil((g.ply_count + 1)/2)) * 100, 1)) AS __avg_toggle_ratio, 
                count(g.game_id) AS __game_count, 
                ugse.rating AS __echess_rating, 
                ugse.total_win_count AS __echess_win_count, 
                ugse.total_loss_count AS __echess_loss_count, 
                ugse.total_draw_count AS __echess_draw_count, 
                (SELECT concat(ugsl.rating,'|',ugsl.total_win_count,'|',ugsl.total_loss_count,'|',ugsl.total_draw_count) FROM user_game_stats_live ugsl WHERE ugsl.user_id = u.user_id AND ugsl.game_time_class = 'lightning') AS __lightning_data, 
                (SELECT concat(ugsl.rating,'|',ugsl.total_win_count,'|',ugsl.total_loss_count,'|',ugsl.total_draw_count) FROM user_game_stats_live ugsl WHERE ugsl.user_id = u.user_id AND ugsl.game_time_class = 'blitz') AS __blitz_data, 
                (SELECT concat(ugsl.rating,'|',ugsl.total_win_count,'|',ugsl.total_loss_count,'|',ugsl.total_draw_count) FROM user_game_stats_live ugsl WHERE ugsl.user_id = u.user_id AND ugsl.game_time_class = 'standard') AS __standard_data, 
                (SELECT uts.rating FROM user_tactics_settings uts WHERE uts.user_id = u.user_id AND uts.attempt_count >= 10) AS __tactics_rating 
              FROM game g 
              JOIN user_game ug ON g.game_id = ug.game_id 
              JOIN user_game_stats_email ugse ON ug.user_id = ugse.user_id 
              JOIN user u ON ug.user_id = u.user_id 
             WHERE g.last_move_time >= DATE_SUB(NOW(), INTERVAL 5 DAY) 
              AND g.ply_count >= 20 
              AND u.is_enabled = 1 
            GROUP BY ug.user_id 
             HAVING __avg_toggle_ratio >= 90 
              AND __game_count >= 10 
            ORDER BY __avg_toggle_ratio DESC', $rsm); 
$query->setParameter(1, 'romanb'); 

$data = $query->getResult();
