MySQL查询未在Phalcon中执行

Question

Using phalcon framework

The purpose of this mysql query is to return the comment count on a forum within the last 1 day:

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

It will run correctly in phpmyadmin but phalcon throws:

Notice: Trying to get property of non-object in C:\\xampp\\htdocs\\sidra\\app\\controllers\\ApiController.php on line 810 Syntax error, unexpected token INTEGER(1), near to ' 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 total_comments DESC (215)

My phalcon codes:

$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();

If there any alternative way to do this?

Answer 1

Your query is correct and works fine on MySQL versions from 4.1 to 5.6.6. So it seems that createQuery() method is trying to parse the query and fails on the INTERVAL clause. I would recommend you to try something like this:

$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();
