Mysql 为每位医生制作一份预约清单；包括医生姓名、患者姓名、日期、时间和持续时间

我有三张桌子

• 医生
• 人
• 任命

表格结构为：

医生表：

+-----------+----------+---------+----------------+----------------+

我需要创建一个查询来生成每个医生的预约列表，包括医生姓名、患者姓名以及预约的日期、时间和持续时间。结果应按医生姓名和预约日期/时间排序

我尝试了以下代码：

select person.last_name, person.initials, person.last_name, appointment.appt_date, appointment.appt_time, appointment.appt_duration -> from doctor inner join appointment on doctor.doctor_id = appointment.doctor_id -> inner join person on person.person_id = appointment.patient_id -> order by person.initials, person.last_name, appointment.appt_date, appointment.appt_time;

我得到了下面的结果，没有医生的名字，而且姓氏有两列，而应该只有一列

+-----------+----------+-----------+------------+-----------+---------------+ 
| last_name | initials | last_name | appt_date  | appt_time | appt_duration | 
+-----------+----------+-----------+------------+-----------+---------------+ 
| Dryden    | A        | Dryden    | 1994-08-10 | 10:10:00  | 10            | 
| Fogg      | F        | Fogg      | 1994-08-10 | 11:30:00  | 10            | 
| Waldon    | K        | Waldon    | 1994-08-10 | 10:10:00  | 10            | 
| Timms     | P        | Timms     | 1994-08-10 | 10:20:00  | 20            | 
| Saj       | T        | Saj       | 2014-03-10 | 12:00:00  | 15            | 
| Williams  | T        | Williams  | 1994-08-10 | 10:00:00  | 10            | 
| Williams  | T        | Williams  | 1994-08-16 | 10:50:00  | 10            | 
| Fisher    | W        | Fisher    | 1994-08-10 | 10:00:00  | 10            | 
| Fisher    | W        | Fisher    | 1994-08-21 | 11:20:00  | 20            |

姓氏提交2次，因为您选择了它2次

select person.last_name, <------ here
person.initials, person.last_name, <---- here
appointment.appt_date, 
appointment.appt_time, 
appointment.appt_duration 
from doctor  
inner join appointment on  doctor.doctor_id = appointment.doctor_id 
inner join person on  person.person_id = appointment.patient_id
order by 
person.initials,
person.last_name, 
appointment.appt_date, 
appointment.appt_time;

不，医生表上没有医生的名字，医生的名字和病人的名字在persons表中。在当前的情况下，可以检索医生的名字，但是我需要将这些带有数据的表发布到sqlfiddle.com上，我们可以进行查询。我的意思是你在sqlfiddle.com中添加表和数据，这样我们就可以看到！！我已经将表格和数据添加到sqlfiddle.com，现在该怎么做欢迎用户3472448。请注意你的问题的表达方式，这样人们可以更容易地理解你的问题，并可能帮助你。在询问模式下，您可以使用帮助部分。（快速或详细）。欢迎再次光临。这个问题很好。你的错误在别处。：-）正如你所看到的，我也没能做到。最好的比“更好”更好。幸亏cpburnz@Strawberry亲爱的朋友，问题最初的显示方式真的很难理解。我试着编辑。我觉得更好。正如你所看到的，cpburnz让它变得更好了。所以请不要对彼此无礼。正如你们所看到的，问题的主人是新来的，所以，我也不是一个专家，但我尽了我最大的努力，就像user3472448@AndreChenier你显然很困惑。

select person.last_name, 
person.initials, 
d.last_name as DoctorName, 
appointment.appt_date, 
appointment.appt_time, 
appointment.appt_duration 
from appointment  
inner join doctor on  doctor.doctor_id = appointment.doctor_id 
left join person on  person.person_id = appointment.patient_id
left join

  select * from person

on  d.person_id = appointment.doctor_id 
order by
