【问题描述】:
我正在 Symfony 3 中编写一个控制台应用程序,但由于某种原因,我的查询结果返回数组中只有 1 个结果,我确认在 MySQL 中运行它并返回几个结果。以下是相关代码:
$arr_id = array();
$em = $this->getContainer()->get('doctrine')->getManager();
$dql2 = 'SELECT r.productId as pid, COUNT(r.id) as cnt
FROM AppBundle:ReferralTrack r
WHERE r.productId in (:in)
GROUP BY r.productId
ORDER BY cnt DESC';
// $arr_id is populated prior to the next command and is, for example, [1,2,3,4,5]
$rt = $em->createQuery($dql2)
->setParameters(
array(
'in' => implode(',', $arr_id),
)
)
;
$traffic_count = $rt->getResult();
当我在 MySql 中运行查询时,与 $rt->getSql() 显示完全相同的查询并替换 ?在从 implode(',', $arr_id) 回显的查询中,我得到类似的结果:
echo print_r( $traffic_count, 1);
---------------------------------
Array
(
[0] => Array
(
[pid] => 11234
[cnt] => 21
)
)
这是我在 MySQL 中运行的查询:
SELECT r0_.product_id AS pid, COUNT( r0_.id ) AS cnt
FROM referral_track r0_
WHERE r0_.product_id
IN ( 11234, 57, 58, 60, 61, 9677, 11216, 11217, 11239, 11296 )
GROUP BY r0_.product_id
ORDER BY cnt DESC
它返回 7 个结果。我注意到的是 getResult() 似乎总是返回最后一条记录,这就是那里显示的数组。怎么回事?
