MySQL Inserting twice and not sure why

[eluser]JamesD[/eluser]

Code:

function start_page()
{
$obj =&get;_instance();
$sql = 'INSERT INTO `site_requests` (`id`, `request`, `referer`, `ip`, `xip`, `type`, `user_agent`, `date`) VALUES (NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL);';
$obj->db->query($sql);
}

Do you need the instance for the query?
Could you not use

Code:

$this->db->query($sql);

without the extra instance?

It looks like that's where it could be squeezing in.
