Question

在我的查询中添加GROUP BY时，Phalcon正在给我一个错误 - Phalcon \ Mvc \ Model \ Exception：语法错误，意外令牌GROUP，靠近＆＃39; BY ...

这是我的代码;

$phql = "
    SELECT $dist $ads_model.id AS id, $ads_model.title AS title, $ads_model.description AS description, $ads_model.country AS country, $ads_model.city AS city, $ads_model.latitude AS latitude, $ads_model.longitude AS longitude, $image_model.file AS image
    FROM $ads_model
    LEFT JOIN $image_model ON $image_model.ad_id = $ads_model.id
    WHERE $where
    GROUP BY $ads_model.id
    $order
    ";
    $ads = $this->modelsManager->executeQuery($phql);

这里是正在生成的查询;

Phalcon\Mvc\Model\Manager->executeQuery(\n SELECT (3959 * acos( cos( radians( xxxx ) ) * cos( radians( \Baseapp\Models\ClassifiedsAds.latitude ) ) * cos( radians( \Baseapp\Models\ClassifiedsAds.longitude ) - radians( xxxx ) ) + sin( radians( xxxx ) ) * sin( radians( \Baseapp\Models\ClassifiedsAds.latitude ) ) ) ) AS distance, 
\Baseapp\Models\ClassifiedsAds.id AS id, \Baseapp\Models\ClassifiedsAds.title AS title, \Baseapp\Models\ClassifiedsAds.description AS description, \Baseapp\Models\ClassifiedsAds.country AS country, \Baseapp\Models\ClassifiedsAds.city AS city, \Baseapp\Models\ClassifiedsAds.latitude AS latitude, \Baseapp\Models\ClassifiedsAds.longitude AS longitude, \Baseapp\Models\ClassifiedsImages.file AS image\n 
FROM \Baseapp\Models\ClassifiedsAds\n 
LEFT JOIN \Baseapp\Models\ClassifiedsImages ON \Baseapp\Models\ClassifiedsImages.ad_id = \Baseapp\Models\ClassifiedsAds.id\n 
WHERE \Baseapp\Models\ClassifiedsAds.status = 'active' Having distance <= 100\n 
GROUP BY \Baseapp\Models\ClassifiedsAds.id\n 
ORDER BY distance ASC\n )

在MySQL中运行查询的简化版本按预期工作。为什么Phalcon搞砸了GROUP BY条款？如果省略GROUP BY，则运行查询。如何让它在PHQL中运行？

另外，作为一个完全相关的问题：我正在使用PHQL，因为Phalcon的分页似乎与原始MySQL无关。有没有办法让Phalcon分页与raw一起工作（不进行自定义分页）？

你的条款顺序错误。

您必须在HAVING之后声明GROUP BY条款。

[GROUP BY {col_name | expr | position}
  [ASC | DESC], ... [WITH ROLLUP]]
[HAVING where_condition]
[ORDER BY {col_name | expr | position}
  [ASC | DESC], ...]

有关完整示例，请参阅mysql docs。
