Query in code igniter keeps returning a "1"

I am a code igniter noob. I have a controller like the following:

<?php
class Welcome extends Controller {
    function Welcome()
    {
        parent::Controller();   
        $this->load->model('usermodel');
    }

    function index()
    {
        $res = $this->db->get('users');
        die( print_r($res) );
    }
}

I have a table 'users' in my database and I have triple checked my database credentials. However, the print method keeps just printing a "1". Anyone know why this simple query would not work?

Also worth noting that print_r prints out an object and i did set active_record = true in my database.php file. In case it helps, this is the output from

print_r($this->db);

prints

UPDATE I tried something like:

$query = $this->db->get("users");
        foreach($query->result() as $row){
            echo "hello";
        }
        die();

with no luck. Still get:

Fatal error: Call to a member function result() on a non-object in ...welcome.php...

$res is a result object, not a string resulting from a successful query. Have you tried calling $res->num_rows() or iterating over $res->result() in a foreach loop and printing out the values of the columns (ex. echo $res->col_name)?

Also (I guess I should have asked this first), are there even any rows in that table?

---

Your query is not returning 1, that's coming from the die statement. The print_r function does not return values unless you pass the 2nd parameter. What is happening is the print_r function is evaluating to true and being printed by the die function.

If you want to see the query results, you have to use the result or result_array functions as explained at http://codeigniter.com/user_guide/database/results.html. There's no shortcut.

---

The correct usage is:

$res = $this->db->get('users');

foreach ($res->result() as $row)
{
    echo $row->title;
}

The actual result data rows are not loaded until you iterate over them.

---

For the query to work correctly, I'd expect you would need to initialize the database class first:

$this->load->database();
$res = $this->db->get('users');

I did have a similar problem. My code is outputing a large PDF and total execution time was above 60 seconds. I thing the connection to the database as lost it self.

Try $this->db->reconnect(); and don't forget to have $db['default']['db_debug'] = TRUE; in your database.php.
