Question

我遇到一个问题，我在Cakephp中有一个Find，旨在寻找在日历应用中忙碌的用户。但是，当我查看MYSQL查询时，它看起来不正确。

查找声明：

$result = $this->EventsUser->find('all',array('conditions'=>array(
                    'OR' =>array( 
                            'AND' => array(
                                    'Event.start >=' => $search_from,
                                    'Event.end <=' => $search_to),
                            'AND' =>array(
                                    'Event.end >' => $search_from,
                                    'Event.end <=' => $search_to),
                            'AND' =>array(
                                    'Event.start >=' => $search_from,
                                    'Event.start <' => $search_to)

                    ),
                    'User.is_resource'=>1

            ),
                    'group'=>array('EventsUser.user_id')
            ));

生成以下MYSQL查询：

SELECT `EventsUser`.`id`, 
   `EventsUser`.`event_id`, 
   `EventsUser`.`user_id`, 
   `EventsUser`.`status_id`, 
   `User`.`id`, 
   `User`.`role_id`, 
   `User`.`username`, 
   `User`.`password`, 
   `User`.`first_name`, 
   `User`.`last_name`, 
   `User`.`photo`, 
   `User`.`photo_dir`, 
   `User`.`email`, 
   `User`.`phone`, 
   `User`.`location`, 
   `User`.`cost_ctr`, 
   `User`.`color`, 
   `User`.`text_color`, 
   `User`.`token`, 
   `User`.`active`, 
   `User`.`is_resource`, 
   `User`.`category_id`, 
   `User`.`description`, 
   `User`.`created`, 
   `User`.`modified`, 
   `User`.`location_id`, 
   `User`.`mobile_number`, 
   `User`.`resource_fuel_card_pin`, 
   `User`.`resource_email_contact`, 
   `User`.`resource_office_hours`, 
   `User`.`resource_post_code`, 
   `User`.`resource_payroll_number`, 
   `User`.`line_manager_email`, 
   ( Concat(`User`.`first_name`, ' ', `User`.`last_name`) ) AS `User__name`, 
   `Event`.`id`, 
   `Event`.`user_id`, 
   `Event`.`name`, 
   `Event`.`description`, 
   `Event`.`start`, 
   `Event`.`end`, 
   `Event`.`all_day`, 
   `Event`.`is_recurring`, 
   `Event`.`recurring_id`, 
   `Event`.`active`, 
   `Event`.`created`, 
   `Event`.`modified`, 
   `Event`.`owner`, 
   `Event`.`cost_cntr_id`, 
   `Event`.`txt_message`, 
   `Event`.`status_id`, 
   `Event`.`reason_for_hire_id`, 
   `Event`.`othersite_postcode`, 
   `Event`.`other_description`, 
   `Event`.`checksheet_id`, 
   `Event`.`declined_notes`, 
   `Event`.`hash` 
FROM   `car_pool`.`events_users` AS `EventsUser` 
   LEFT JOIN `car_pool`.`users` AS `User` 
          ON ( `EventsUser`.`user_id` = `User`.`id` ) 
   LEFT JOIN `car_pool`.`events` AS `Event` 
          ON ( `EventsUser`.`event_id` = `Event`.`id` ) 
WHERE  ( ( `Event`.`end` > '2015-06-07 13:01' ) 
     AND ( `Event`.`end` <= '2015-06-12 13:01' ) ) 
   AND `User`.`is_resource` = '1' 
GROUP  BY `EventsUser`.`user_id`

似乎缺少AND语句。当我从find中删除AND语句时，它总是在查找

上执行最后一个

有人有任何想法吗？

Answer 1

PHP 101，在关联数组中多次使用相同的键将覆盖以前的值。您多次使用'AND'。只需删除'AND'键，因为ANDing是默认行为。

Answer 2

您的OR数组未正确定义。您创建了一个包含3个相同键的数组（即“AND”）

而不是：

'OR' =>array( 
            'AND' => array(
                          'Event.start >=' => $search_from,
                          'Event.end <=' => $search_to),
            'AND' =>array(
                          'Event.end >' => $search_from,
                          'Event.end <=' => $search_to),
            'AND' =>array(
                          'Event.start >=' => $search_from,
                          'Event.start <' => $search_to)
                )

应该是这样的：

'OR' =>array( 
            array('AND' => array(
                          'Event.start >=' => $search_from,
                          'Event.end <=' => $search_to)),
            array('AND' =>array(
                          'Event.end >' => $search_from,
                          'Event.end <=' => $search_to)),
            array('AND' =>array(
                          'Event.start >=' => $search_from,
                          'Event.start <' => $search_to))
                )

CakePHP在Query上缺少AND语句
