Question

这是我的表格

 create table guest (

             guest_id           int auto_increment primary key unique not null,
             guest_lname        varchar(50) not null,
             guest_fname        varchar(50) not null,

             guest_email        varchar(100) not null,
             guest_password     varchar(50) not null,
             guest_address      varchar(20) not null,
             guest_op_adres     varchar(200),
             guest_gender       int(1) not null,
             guest_mobile_no    varchar(15) not null
            );

  create table room_rate_default (
     defroom_rateID      int auto_increment not null primary key,
     room_typeID int not null,
     defseason_type  varchar(50) not null,
     defmonRate      double not null,
     deftuesRate double not null,
     defwedRate      double not null,
     defthuRate      double not null,
     deffriRate      double not null,
     defsatRate      double not null,
     defsunRate      double not null,
     foreign key(room_typeID)references room_type(room_typeID)
     );

 create table room_rate (
     room_rateID     int auto_increment not null primary key,
     room_typeID     int not null,
     season_type     varchar(50) not null,
     monRate         double not null,
     tuesRate       double not null,
     wedRate     double not null,
     thuRate     double not null,
     friRate     double not null,
     satRate     double not null,
     sunRate     double not null,
     adult       int,
     children    int,
     foreign key(room_typeID)references room_type(room_typeID)
     );


  create table room_type (
         room_typeID    int auto_increment not null primary key,
     room_type   varchar(50) not null,
     room_type_des  varchar(200)
     );

   create table room (
       room_id          int unique primary key auto_increment not null,
       room_number      int unique not null,
       room_typeID      int not null,
       room_adultcapacity    int not null,
       room_childcapacity    int not null,
       room_img         varchar(100),
       room_status      int(1),
       foreign key(room_typeID)references room_type(room_typeID)
        );

  create table reservation ( 
      reserve_code          varchar(20) primary key unique not null,       
      guest_id              int not null,
      foreign key(guest_id)references guest(guest_id),
      room_id          int,
      foreign key(room_id)references room(room_id),
      reserve_date_start         date,
      reserve_date_end          date,
      reserve_status      int(1)
     );

这是记录

INSERT INTO `reservation` (`reserve_code`, `guest_id`, `room_id`, `reserve_date_start`, `reserve_date_end`, `reserve_status`) VALUES
    ('p28ypfgWO3Ijfn3eO5Vk', 18, NULL, 2, '2018-06-18', '2018-06-22', 1),
    ('67Bs8MKTOjZ2eJ9fxMPF', 18, NULL, 3, '2018-06-24', '2018-06-29', 1);


INSERT INTO `room` (`room_id`, `room_number`, `room_typeID`, `room_adultcapacity`, `room_childcapacity`, `room_img`, `room_status`) VALUES
    (2, 102, 2, 2, 2, '../image-upload/room7.jpg', 1),
      (3, 103, 2, 2, 2, '../image-upload/room8.jpg', 1),
    (4, 104, 3, 2, 2, '../image-upload/room9.jpg', NULL),
    (5, 105, 3, 2, 1, '../image-upload/room10.jpg', NULL);

这是从表单检查可用性中检入和签出日期

desire-check-in-dates date("2018-06-17")
desire-check-out-dates date("2018-06-23")

这是我的查询

    "select distinct room_type.room_type, room_type.room_typeID, room_type.room_type_des, room.room_id, room.room_number, room.room_typeID, room.room_adultcapacity, room.room_childcapacity, room.room_img, room.room_status
                     from room 
left outer  join room_type on room.room_typeID = room_type.room_typeID 
left outer join room_rate_default on room_type.room_typeID = room_rate_default.room_typeID
left outer join room_rate on room_type.room_typeID = room_rate.room_typeID
                     where room.room_id not in ('select room_id from reservation where date('2018-06-17') between 
               reserve_date_start and reserve_date_end or date('2018-06-23') between 
               reserve_date_start and reserve_date_end or date('2018-06-17') < 
               reserve_date_start and date('2018-06-23') > reserve_date_end') or room.room_status is null";

我不知道我的查询错误是什么.. 在这个查询中我想显示room_id 3,4和5，但我的查询不起作用..

此查询现在正在运行这是我的问题的答案谢谢你先生@ P.Salmon寻求帮助

select distinct room_type.room_type, room_type.room_typeID, room_type.room_type_des, room.room_id, room.room_number, room.room_typeID, room.room_adultcapacity, room.room_childcapacity, room.room_img, room.room_status
                     from room left outer  join room_type on room.room_typeID = room_type.room_typeID left outer join room_rate_default on room_type.room_typeID = room_rate_default.room_typeID
                     left outer join room_rate on room_type.room_typeID = room_rate.room_typeID
                     where room.room_id not in (select room_id from reservation where date('2018-06-17') between 
                     reserve_date_start and reserve_date_end or date('2018-06-23') between 
                     reserve_date_start and reserve_date_end or date('2018-06-17') < 
                     reserve_date_start and date('2018-06-23') > reserve_date_end) or room.room_status is null

我的查询有什么不对？
