从Codeigniter中的数据库检索结果

Question

As I know so far, we can use

$result = $query->row_array();

to retrieve the single value from the database and

$result = $query->result_array();

to retrieve multiple values from the database.

In this case I am using the particular table CRUD options. So instead of writing

$rows = $query->num_rows();
if( $rows > 1 ){
    $result = $query->result_array();
}
if( $rows == 1 ){
    $result = $query->row_array();
}

Is there any other way to write the query even if the table has only a single row or multiple row?

Please guide me. Thanks in advance friends

Answer 1

You can try this way

$query = $this->db->query("YOUR QUERY");

if ($query->num_rows() > 0)
{
   foreach ($query->result() as $row)
   {
      echo $row->title;
      echo $row->name;
      echo $row->body;
   }
}

if you want check one row or multiple row

 $query = $this->db->query("YOUR QUERY");

    if ($query->num_rows() == 1)
    {
       foreach ($query->result() as $row)
       {
          echo $row->title;
          echo $row->name;
          echo $row->body;
       }
    }else if($query->num_rows() > 1){
       foreach ($query->result() as $row)
       {
          echo $row->title;
          echo $row->name;
          echo $row->body;
       }
}else{
    echo 'No any records in data base';
}

it's doesn't matter one record or more

Answer 2

Try this:

$query = $this->db->query("YOUR QUERY");
if ($query->num_rows() > 0)
{
    return $query->result();
}else{
    return false;
}

Answer 3

$result=$this->db->count_all("table_name")>1?$this->db->get("table_name")->result_array():$this->db->get("table_name")->row_array();
echo "<pre>";
print_r($result);
