在 Yii2 中执行原始 SQL 查询?
Performing raw SQL queries in Yii2?
我在将 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 个赌注。我试过很多 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...
投注:
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是我根据time()
计算的6个月的时间段另外请注意balance_return
是用户获得的每一次胜利所以它的总和决定了排名。
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
");
你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();

第一个参数是 sql(带占位符),第二部分是要与占位符一起使用的值数组。
