我的 SQL 脚本没问题，但我无法在 Laravel 6 中编写此 SQL 脚本

Question

SELECT appointmentDate 
     , appiontmentTime
     , (SELECT GROUP_CONCAT(name) name
          FROM users ta 
          JOIN appointment u 
            ON u.salesperson = ta.id   
         WHERE u.appiontmentTime = appt.appiontmentTime 
           AND u.appointmentDate = appt.appointmentDate
        ) usersname  
  FROM appointment appt 
 WHERE appointmentDate BETWEEN "2020-05-01" AND "2020-05-31" 
 GROUP 
    BY appointmentDate
     , appiontmentTime

Answer 1

我看不出有什么理由需要这里的子查询。我认为以下查询应该 return 相同的结果：

SELECT a.appointmentDate 
     , a.appiontmentTime
     , GROUP_CONCAT(u.name) name
FROM appointment a
LEFT JOIN users u ON u.id = a.salesperson
WHERE a.appointmentDate BETWEEN "2020-05-01" AND "2020-05-31" 
GROUP 
    BY a.appointmentDate
     , a.appiontmentTime

使用 laravels 查询生成器它将是：

$data = DB::table('appointment as a')
    ->leftJoin('users as u', 'u.id',  '=', 'a.salesperson')
    ->whereBetween('a.appointmentDate', ['2020-05-01', '2020-05-31'])
    ->groupBy('a.appointmentDate', 'a.appiontmentTime')
    ->select('a.appointmentDate', 'a.appiontmentTime')
    ->selectRaw('GROUP_CONCAT(u.name) as name')
    ->get();
