MySQL查詢中爾康

Question

不執行使用爾康框架

這個MySQL查詢的目的是要在一個論壇上返回的最後1天之內評論數：

SELECT fc.forum_id, count(fc.forum_id) AS total_comments 
FROM forum_comments AS fc 
WHERE DATE_SUB(CURDATE() , INTERVAL 1 
DAY) <= fc.updated_at 
GROUP BY fc.forum_id 
ORDER BY total_comments DESC 
LIMIT 0 , 30 

它將在phpMyAdmin正常運行但多爾康拋出：

說明：試圖讓用C非對象的屬性：\ XAMPP \ htdocs中\錫德拉\應用\控制器\ ApiController.php上線810中的語法錯誤，意外的標記INTEGER（1），靠近'DAY）< = fc.updated_at GROUP BY fc.forum_id ORDER BY total_comments DESC'，when parsing：SELECT fc.forum_id，count（fc.forum_id）as total_comments FROM ForumComments as fc WHERE DATE_SUB（CURDATE（），INTERVAL 1 DAY）< = fc .updated_at GROUP BY fc.forum_id ORDER BY DESC TOTAL_COMMENTS個（215）

我爾康代碼：

$sql = "SELECT fc.forum_id,count(fc.forum_id)as total_comments ". 
       "FROM ForumComments as fc ". 
       "WHERE DATE_SUB(CURDATE() , INTERVAL 1 
       DAY) <= fc.updated_at ". 
       "GROUP BY fc.forum_id ". 
       "ORDER BY total_comments DESC "; 

     $query = $this->modelsManager->createQuery($sql); 
     $staff = $query->execute()->toArray(); 

如果有任何替代辦法做到這一點？

Answer 1

您的查詢是正確的，並在4.1到5.6.6的MySQL版本上正常工作。所以看起來createQuery()方法試圖解析查詢並且在INTERVAL子句上失敗。我會建議你嘗試這樣的事情：

$yesterday = date('Y-m-d', strtotime("-1 days")); 

$sql = "SELECT fc.forum_id,count(fc.forum_id)as total_comments ". 
      "FROM ForumComments as fc ". 
      "WHERE '$yesterday' <= fc.updated_at ". 
      "GROUP BY fc.forum_id ". 
      "ORDER BY total_comments DESC "; 

$query = $this->modelsManager->createQuery($sql); 
$staff = $query->execute()->toArray();
