Mysql 在 Yii2 中执行原始 SQL 查询

在将PHP网站迁移到Yii2框架时，我编写了以下查询.我想将它们添加到我的控制器中，以便显示赢得的前10个赌注.我try 了很多Yii2数据库类，但我无法让它工作.

我的桌子是:

users:

id | user_name | user_status | ...other columns...

bets:

id | user_id | date_time |...other columns...| balance_return

我想在Yii2中得到的查询是:

$query_all = $dbh->query("
    SELECT SUM(bets.balance_return) AS total_win
         , bets.user_id
         , users.user_name
         , users.user_status
      FROM bets INNER JOIN users ON bets.user_id = users.id
     WHERE users.user_status = 'verified'
       AND bets.date_time > " . $start_date . "
  GROUP BY bets.user_id
  ORDER BY total_win DESC
");

变量start_date是一个6个月的周期，我根据time()计算.请注意，balance_return是用户获得的每一次胜利，因此其总和决定排名.

第二个问题是:

$qwi = $dbh->query("
    SELECT SUM(bets.balance_return) AS total_win
         , bets.user_id
         , users.user_name
         , users.user_status
      FROM bets INNER JOIN users ON bets.user_id = users.id
     WHERE users.user_status = 'verified'
       AND bets.date_time > " . $start_date . "
  GROUP BY bets.user_id
  ORDER BY total_win DESC LIMIT 0,10
");
