在CakePhp中创建不查询

Question

如何在CakePhp中执行此查询？

从id不在的用户中选择id（从user_details中选择userid ud join users u ON u.id = ud.userid AND ud。name ='fullname'）;

Answer 1

获取您必须执行的确切查询：

$this->User->find(
    'all',
    array(
        'fields' => array('User.id'),
        'conditions' => array('id NOT IN (select userid from user_details ud join users u ON u.id=ud.userid AND ud.name ='fullname')' 
    );

但你可以简单地实现相同的结果

$this->User->find(
    'all',
    array(
        'fields' => array('User.id'),
        'conditions' => array('UserDetail.name !=' => 'fullname'),
        'contain' => array('UserDetail')
    );

假设您的User模型处于真实状态（hasOne？）并且UserDetail

Answer 2

最简单的方法。但不是本地的cakephp，总是试着用find（）方法。

$this->User->Query("select id from users where id not in (select userid from user_details ud join users u ON u.id=ud.userid AND ud.name ='fullname')");
