如何在数据库中搜索并使用codeigniter将最后一行作为数组返回

Question

i want to search in two columns and select last record and send it as array to controller to show data

 public function show_data($post_code,$fname){
    $this->db->where('post_code',$post_code);
    $this->db->where('fname',$fname);

    $query=$this->db->get('customer');
    return $query->result_array();}

it finds my desire records but i want to show last record, i used order_by(), limit() function but they don't work properly and affected my data entries in database. what's wrong? how can i correct it? thank you

Answer 1

my solution is :

    public function show_data($post_code,$fname){
    $this->db->where('post_code',$post_code);
    $this->db->where('fname',$fname);
    $this->db->order_by("id", "desc");
    $this->db->limit(1);
    $query=$this->db->get('customer');
    return $query->result_array();
}

thank you saty

Answer 2

$query = $this->db->query("SELECT * FROM TABLE_NAME WHERE COLUMN_NAME=$COLUMN_NAME AND SECOND-COLUMN_NAME=$SECOND-COLUMN_NAME ORDER BY id DESC LIMIT 1")->result();
return $query;

This will return you last row you created.
