我将PHP网站迁移到Yii2框架时编写了以下查询。我想将它们添加到我的控制器中,以显示赢得的前10个投注。我尝试过很多Yii2数据库类,但我无法让它工作。
我的表是:
用户:
id | user_name | user_status | ...other columns...
赌注:
id | user_id | date_time |...other columns...| balance_return
我希望在Yii2中获得的查询是:
$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是我根据time()
计算的6个月的时间段。另请注意,balance_return
是用户获得的每一次胜利,因此其总和决定了排名。
第二个查询是:
$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
");
答案 0 :(得分:69)
您可以像这样执行原始SQL
$connection = Yii::$app->getDb();
$command = $connection->createCommand("
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", [':start_date' => '1970-01-01']);
$result = $command->queryAll();
我建议阅读:http://www.yiiframework.com/doc-2.0/yii-db-connection.html#createCommand()-detail
第一个参数是sql(带占位符),第二个参数是要与占位符一起使用的值数组。
