我怎样才能在 CakePHP 中添加它？我尝试了我所知道的一切，但不起作用：

        select
            card_type
            ,sum (case when used = 'Y' then (select amount from auth a1 where a1.origid = a.pnref and trxtype = 'D') else amount end) as total
        from    auth a
        where
            add_date between '$this->date1' and '$this->date2'
            and     (trxtype = 'S' or trxtype = 'F')
            and     user_num = $this->user_num
            and     pnref not in (select    origid
                                    from        auth a
                                    where       add_date between '$this->date1' and '$this->date2'
                                    and trxtype = 'V')
        group by card_type
        order by 1
  • 字段中的子查询
  • 子查询在哪里

[我试试这个]：

    $conditionsSubQuery['"Auth2"."add_date BETWEEN ? AND ?"'] = array($inicial_date, $final_date);
    $conditionsSubQuery['"Auth2"."trxtype"'] = 'V';

    $db = $this->User->getDataSource();
    $subQuery = $db->buildStatement(
        array(
            'fields'     => array('"Auth2"."origid"'),
            'table'      => 'auth',
            'alias'      => 'Auth2',
            'limit'      => null,
            'offset'     => null,
            'joins'      => array(),
            'conditions' => $conditionsSubQuery,
            'order'      => null,
            'group'      => null
            ),
        $this->Auth
    );

    $subQuery = ' "Auth"."pnref" NOT IN (' . $subQuery . ') ';
    $subQueryExpression = $db->expression($subQuery);

    $conditions[] = $subQueryExpression;
    $conditions[] = array(
        'Auth.date BETWEEN ? and ?' => array($inicial_date, $final_date),
        'OR' => array(
            'Auth.trxtype' => 'S',
            'Auth.trxtype' => 'F'
        ),
        'Auth.user_num' => $user_num
    );

    $fields = array(
        'Auth.card_type',
        "sum (case when Auth.used = 'Y' then (select Auth2.amount from auth Auth2 where Auth2.origid = Auth.pnref and Auth.trxtype = 'D') else Auth.amount end) as Auth.total"
    );

    $group = array('Auth.card_type');
    $order = array(1);

    return $this->Auth->find('all', compact('fields', 'conditions', 'group', 'order'));

[错误]

总之感谢。

就像@Chris Traveres评论一样，只是一个语法错误。

查询中的问题很明显，标识符关联不正确。错误消息查询的相关子句是“Auth2”。“add_date BETWEEN '2013/02/19 06:00:00' AND '2013/02/22 10:34:17'”我怀疑你有一个布尔列命名为“add_date BETWEEN '2013/02/19 06:00:00' AND '2013/02/22 10:34:17'”所以问题应该仅限于 CakePHP 语法

问题解决了！多谢你们。
