How to use subquery in Yii
The first step is to create a subquery, which can be Created based on yii\db\Query or based on Model.
$subQuery = Order::find() ->where(['user_id' => $userId]) ->andWhere(['status' => $status]);
You can also add sorting and paging, for example:
$subQuery->orderBy(['id' => SORT_ASC]) ->offset($offset) ->limit($pageSize);
Then we can use this subquery in our main query, as long as it is a place where subqueries can be written in mysql , you can use this subquery directly.
$list = (new Query())->select($field) ->from(['order' => $subQuery]) // 在这里使用了子查询 ->leftJoin(['goods' => OrderGoods::tableName()], 'order.id = goods.order_id') ->createCommand() ->queryAll();
Finally generated statement
SELECT * FROM ( SELECT * FROM `od_order` WHERE ( `user_id` = '1' ) ORDER BY `id` ASC LIMIT 10 OFFSET 1 ) `order` LEFT JOIN `od_order_goods` `goods` ON `order`.id = goods.order_id
