Question

我的模型有问题，如何获取以下选择查询中的所有列：

public function getAllProvince($where = array())
{
    $this->db->select("id, name");
    $this->db->from('target_statis');
    $this->db->where($where); 
    $this->db->group_by("id, name"); 
    $this->db->order_by("id"); 
    $query = $this->db->get();
    if ($query->num_rows() > 0){  
        return $query->result(); 
    } 
    return false;
}

Answer 1

尝试一下

public function getAllProvince($where = array()){
        $this->db->select("*");//changed line
        $this->db->from('target_statis');
        $this->db->where($where); 
        $this->db->group_by("id,name"); 
        $this->db->order_by("id"); 
        $query = $this->db->get();
        if ($query->num_rows() >0){  
            return $query->result(); 
        }else{ 
            return array();//changed line
        }
    }

Answer 2

我要删除$this->db->select(column)，因为您想获取所有列

如果您未定义$this->db->select()，codeigniter将默认选择所有列

另外，我要删除$this->db->from()并将表名移至$this->db->get('target_statis');

public function getAllProvince($where = array()){
    $this->db->where($where); 
    $this->db->group_by("id,name"); 
    $this->db->order_by("id"); 
    $query = $this->db->get('target_statis'); 
    if ($query->num_rows() >0){  
        return $query->result(); 
    } 
    return FALSE;
}

尝试此代码...

 public function getAllProvince($where = array())
    {
        $this->db->select("*");
        $this->db->from('target_statis');
        $this->db->where($where); 
        $this->db->group_by("id, name"); 
        $this->db->order_by("id"); 
        $query = $this->db->get();
        if ($query->num_rows() > 0){  
            return $query->result(); 
        } 
        return false;
    }
