CakePHP 2.3中字段和位置中的子查询
我怎么能用CakePHP点画呢? 我尝试了我知道的一切,但都不起作用:CakePHP 2.3中字段和位置中的子查询,php,cakephp,Php,Cakephp,我怎么能用CakePHP点画呢? 我尝试了我知道的一切,但都不起作用: 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 whe

- 字段中的子查询
- 子查询在何处
[我尝试一下]:
$conditionsSubQuery['"Auth2"."add_date BETWEEN ? AND ?"'] = array($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]

无论如何,谢谢。就像@christraveres评论一样,这只是一个语法错误
查询中的问题很明显,标识符是 没有正确的联系。错误的相关条款 邮件的查询为“Auth2”。“添加日期介于'2013/02/19 06:00:00'和' “2013/02/22 10:34:17”,我怀疑您是否有一个名为 “添加日期在'2013/02/19 06:00:00'和'2013/02/22 10:34:17'之间”so 问题真的应该局限于CakePHP语法 问题解决了!
谢谢大家。显示您尝试过的代码。至少对于子查询(选择origid…),我会保持简单,并使用一个单独的查询,然后使用该查询的结果作为第二个查询的筛选器/条件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”。“在'2013/02/19 06:00:00'和'2013/02/22 10:34:17'之间添加日期”
,我怀疑您是否有一个名为“在'2013/02/19 06:00:00'和'2013/02/22 10:34:17'之间添加日期”的布尔列。
所以问题真的应该限于CakePHP语法。@ChrisTravers谢谢,你说得对(已经过了多少时间,所以,现在我用$this->query()方法运行原始查询)。
