Question

我怎样才能在mysql数据库中查询到codeigniter框架。我的查询显示不等于admin的位置。这是我的查询

$query = $this->db->query('SELECT tbl_user_type.position, tbl_users.user_id, tbl_users.user_fname, tbl_users.user_lname,
                    tbl_users.user_mname FROM tbl_users INNER JOIN tbl_user_type ON tbl_users.user_type = tbl_user_type.user_type 
                    WHERE !(tbl_user_type.position = Admin) ');
        return $query->result();

Answer 1

尝试一下。

$query = $this->db->query('SELECT tbl_user_type.position, tbl_users.user_id, tbl_users.user_fname, tbl_users.user_lname,
                tbl_users.user_mname FROM tbl_users INNER JOIN tbl_user_type ON tbl_users.user_type = tbl_user_type.user_type 
                WHERE tbl_user_type.position != "Admin" ');
    return $query->result();

OR

    $query = $this->db->query('SELECT tbl_user_type.position, tbl_users.user_id, tbl_users.user_fname, tbl_users.user_lname,
                tbl_users.user_mname FROM tbl_users INNER JOIN tbl_user_type ON tbl_users.user_type = tbl_user_type.user_type 
                WHERE tbl_user_type.position <> "Admin" ');
    return $query->result();

Answer 2

试试吧......

$this->db->where('tbl_user_type.position !=','Admin');
$query = $this->db->query('SELECT tbl_user_type.position, tbl_users.user_id, tbl_users.user_fname, tbl_users.user_lname,
                    tbl_users.user_mname FROM tbl_users INNER JOIN tbl_user_type ON tbl_users.user_type = tbl_user_type.user_type');
 return $query->result();

Answer 3

请使用活动记录查询来执行此任务，使用codeigniter中的活动记录会更简单。

$this->db->select("UT.position, U.user_id, U.user_fname, U.user_lname, U.user_mname");
$this->db->from("tbl_users AS U");
$this->db->join("tbl_user_type AS UT", "U.user_type = UT.user_type"); 
$this->db->where("UT.position !=", "Admin");
$query = $this->db->get();

return $query->result();

用上面的代码替换您的查询。它会解决你的问题。

codeigniter不等于查询错误
