重新排列codeigniter mysql

Question

如何加入下面的兩個函數並使它們在同一個$qry內？

public function get_page_likes() { 
    $qry = $this->db->query("SELECT p.id, p.tid, IF(SUM(pl.like) > 0, SUM(pl.like), 0) AS likes FROM pages_test AS p LEFT JOIN page_likes_test pl ON p.id = pl.pid AND p.tid = pl.tid GROUP BY p.tid, p.id HAVING likes >= 0 ORDER BY p.id, p.tid"); 
    return $qry->result_array(); 
} 

public function get_page_dislikes() { 
    $qry = $this->db->query("SELECT p.id, p.tid, IF(SUM(pl.dislike) > 0, SUM(pl.dislike), 0) AS dislikes FROM pages_test AS p LEFT JOIN page_likes_test pl ON p.id = pl.pid AND p.tid = pl.tid GROUP BY p.tid, p.id HAVING dislikes >= 0 ORDER BY p.id, p.tid"); 
    return $qry->result_array(); 
}

Answer 1

更改查詢像

$qry = $this->db->query("SELECT p.id, p.tid, SUM(pl.like) AS likes, SUM(pl.dislike) AS dislikes FROM pages_test AS p LEFT JOIN page_likes_test pl ON p.id = pl.pid AND p.tid = pl.tid GROUP BY p.tid, p.id"); 

回報$ qry-> result_array（）;

public function get_page_likes_dislikes(){ 

    return $this->db->select('p.id, p.tid, IF(SUM(pl.like) > 0, SUM(pl.like), 0) AS likes, IF(SUM(pl.dislike) > 0, SUM(pl.dislike), 0) AS dislikes') 
     ->join('page_likes_test pl', 'p.id = pl.pid AND p.tid = pl.tid', 'left') 
     ->group_by('p.tid, p.id') 
     ->order_by('p.id, p.tid') 
     ->get('pages_test p')->result_array(); 
}
