Yii2如何在活动记录中使用内置的mysql功能

Question

如何在Yii2活动记录中使用内置的MySQL函数？ 这是我要隐藏在活动记录中的查询。

以及如何在SearchModel中实现相同功能？

SELECT * FROM `dts_track` where concat(date_received,time_received) != concat(date_released,time_released)

Answer 1

您可以将字符串格式用于

public function search($params)
{
    $query = YourModel::find();

    $dataProvider = new ActiveDataProvider([
        'query' => $query,
    ]);

    if (!($this->load($params) && $this->validate())) {
        return $dataProvider;
    }

    $query->andWhere('concat(date_received,time_received) != concat(date_released,time_released)');

    return $dataProvider;
}

Answer 2

在搜索功能中，让我为更好的生活做出贡献：

        if(isset($params['date_received']) AND isset($params['time_received'])){
            $datereceived = $params['date_received'].$params['time_received'];
        }

        if(isset($params['date_released']) AND isset($params['time_released'])){
            $datereleased = $params['date_released'].$params['time_released'];
        }

        $query->andWhere(':date1 != :date2', [':date1' => $datereceived , ':date2' => $datereleased ]);
