我正在尝试查找用户输入的日期是否与数据库上的任何日期重叠。

我已经把 SQL 语句写下来了（可能需要一些调整，将测试），但我正在努力将它正确地放入 cakePHP。

我有什么

$result = $this->find('all', array(
    'conditions' => array(
        'OR' => array(
            'AND' => array(
                array('BoardroomBooking.start_time >=' => $this->data['BoardroomBooking']['start_time']),
                array('BoardroomBooking.start_time <' => $this->data['BoardroomBooking']['start_time'])
            ),
            'AND' => array(
                array('BoardroomBooking.start_time <=' => $this->data['BoardroomBooking']['start_time']),
                array('BoardroomBooking.start_time >' => $this->data['BoardroomBooking']['end_time'])
            )
        )
    )
));

它创造了什么

SQL Query: SELECT `BoardroomBooking`.`id`, `BoardroomBooking`.`name`,
`BoardroomBooking`.`boardroom_id`, `BoardroomBooking`.`date`, 
`BoardroomBooking`.`start_time`, `BoardroomBooking`.`end_time`, 
`BoardroomBooking`.`notes`, `BoardroomBooking`.`recurrence_id`, 
`BoardroomBooking`.`created`, `BoardroomBooking`.`modified`, `Boardroom`.`id`, 
`Boardroom`.`name`, `Boardroom`.`created`, `Boardroom`.`modified` FROM 
`intraweb_db`.`boardroom_bookings` AS `BoardroomBooking` LEFT JOIN 
`intraweb_db`.`boardrooms` AS `Boardroom` ON (`BoardroomBooking`.`boardroom_id`
 = `Boardroom`.`id`) WHERE ((`BoardroomBooking`.`start_time` <= '12:55:00') AND 
(`BoardroomBooking`.`start_time` > '13:00:00'))

我想要的是

SQL Query: SELECT `BoardroomBooking`.`id`, `BoardroomBooking`.`name`,
`BoardroomBooking`.`boardroom_id`, `BoardroomBooking`.`date`, 
`BoardroomBooking`.`start_time`, `BoardroomBooking`.`end_time`, 
`BoardroomBooking`.`notes`, `BoardroomBooking`.`recurrence_id`, 
`BoardroomBooking`.`created`, `BoardroomBooking`.`modified`, `Boardroom`.`id`, 
`Boardroom`.`name`, `Boardroom`.`created`, `Boardroom`.`modified` FROM 
`intraweb_db`.`boardroom_bookings` AS `BoardroomBooking` LEFT JOIN 
`intraweb_db`.`boardrooms` AS `Boardroom` ON (`BoardroomBooking`.`boardroom_id`
 = `Boardroom`.`id`) WHERE (`BoardroomBooking`.`start_time` >= '12:55:00' AND 
`BoardroomBooking`.`start_time` < '12:55:00') OR (`BoardroomBooking`.`start_time`
 <= '12:55:00') AND (`BoardroomBooking`.`start_time` > '13:00:00'))

我已经阅读了有关如何检索数据的文档，但是对于我的生活来说，它无法按照我想要的方式工作。

现在，我可能不正确，但我相信您的问题在您的数组声明中：

  array(
    'AND' => array(
      ...
    ),
    'AND' => array(
      ...
    )
  )

就 PHP 而言，您刚刚在数组中声明了一个“AND”键，然后重新分配了它。根据Cake Cookbook，您需要在不同的数组中声明相同的字段：

'OR' => array(
  array('AND' => array (...)),
  array('AND' => array (...))
)

这应该可以防止查询将您的两个条件视为同一事物并覆盖条目。
