Yii2高級排序

Question

如何在Yii2中實現以下排序：

SELECT * FROM `orders` order by case when status != 'ORDER_DONE' then 1 else 2 end,status

我想將ORDER_DONE的狀態放到底部。 任何想法？

Answer 1

從2.0.7版本開始，您可以將yii\\db\\Expression傳遞給orderBy()所以可以這樣：

(new \yii\db\Query)
->from('orders')
->orderBy(new \yii\db\Expression('CASE WHEN status != "ORDER_DONE" THEN 1 ELSE 2 END, status'))
->all();

要對數據提供者進行排序，請使用：

'sort' => [
    'attributes' => [
        'onlinedate' => [
            'asc' => [new \yii\db\Expression('CASE WHEN status != "ORDER_DONE" THEN 1 ELSE 2 END, status')],
            'desc' => [new \yii\db\Expression('CASE WHEN status = "ORDER_DONE" THEN 1 ELSE 2 END, status')],
        ],
    ],
]
