如何將sql查詢更改爲yii2

Question

如何將以下sql查詢更改爲yii2。

SELECT 
    a.id, a.name_of_flight, a.time_of_flight, (no_of_passenger-b.cnt) as avail 
FROM 
    flight_schedule a 
LEFT JOIN 
    (SELECT flight_time, COUNT(id) AS cnt FROM book_eticket WHERE flight_date='2016-06-01' GROUP BY flight_time) b 
ON a.id = b.flight_time 

Answer 1

我不確定，但你可以使用這個邏輯。 欲瞭解更多詳情請訪問official頁面。

flight_schedule::find() 
    ->select(['id', 'name_of_flight', ' time_of_flight']) 
    ->distinct() 
    ->joinWith('bookEticket') 
    ->all(); 

並添加有關flight_schedule型號：

public function getBookEticket() 
{ 
    $this->hasOne(book_eticket::className(), ['id' => 'flight_time']); 
}
