sql查詢在gridview中的foreach yii2

Question

在第一列的gridview中我有一個快遞列表。我需要爲每位快遞員計算訂單數量。在SQL它看起來像

SELECT order_customFields.order_customFields_delivery_method, 
    sum(case `order`.order_status when 'sent' then 1 else 0 end) paid 
FROM order_customFields 
    INNER JOIN `order` ON order_customFields.order_id = `order`.order_id 
WHERE 
    order_customFields.order_customFields_order_date >= '2016-12-01' AND 
    order_customFields.order_customFields_order_date <= '2016-12-31' 
AND order_customFields.order_customFields_delivery_method = eu_dpd; 

如果我創建快遞陣列並做到這一點的foreach中的SQL查詢，像

`$courier = [eu_dpd,eu_dhl,eu_ups] 
foreach ($courier as $value) { 
    SELECT order_customFields.order_customFields_delivery_method, 
    sum(case `order`.order_status when 'sent' then 1 else 0 end) paid 
FROM order_customFields 
    INNER JOIN `order` ON order_customFields.order_id = `order`.order_id 
WHERE 
    order_customFields.order_customFields_order_date >= '2016-12-01' AND 
    order_customFields.order_customFields_order_date <= '2016-12-31' 
AND order_customFields.order_customFields_delivery_method = $value; 
}` 

如何將其應用於yii2？

Answer 1

複雜查詢的簡單方法是基於正常的數據庫連接上

$yourModel = Yii::$app->db->createCommand(
    "SELECT order_customFields.order_customFields_delivery_method as deliver_method, 
     sum(case `order`.order_status when 'sent' then 1 else 0 end) paid 
    FROM order_customFields 
    INNER JOIN `order` ON order_customFields.order_id = `order`.order_id 
    WHERE order_customFields.order_customFields_order_date >= '2016-12-01' 
    AND order_customFields.order_customFields_order_date <= '2016-12-31' 
    AND order_customFields.order_customFields_delivery_method = '" .$value . "';")->queryOne(); 

那麼createCommand你可以參考結果作爲

echo $yourModel['deliver_method']; 
echo $yourModel['paid']; 

爲GridView控件，你可以使用的SqlDataProvider和通dataProvider到您的視圖http://www.yiiframework.com/doc-2.0/yii-data-sqldataprovider.html
