Strange database error: Trailing zero in SQL?

All-

Working on an enhancement to a site and running into a strange query issue.

Here's my controller:

Code:

if($this->session->userdata('logged_in')) {

                $data = array('couponData' => $this->user->getUserCouponInfoByOrganization($this->user->getUserId($this->session->userdata('user_email')),$this->input->post('organization_id')));
                $this->load->view('header');
                $this->load->view('view_coupons', $data);
                $this->load->view('footer');
        } else {

Here's the "getUserCouponInfoByOrganization" method:

Code:

function getUserCouponInfoByOrganization($user_id, $organization_id)
    {
        $this->db->from('coupon, users, organizations');
        $where = "coupon.coupon_user_id = $user_id AND users.user_id = $user_id AND coupon.coupon_organization_id = $organization_id AND organizations.organization_id = $organization_id";
        $this->db->where($where);
        $query = $this->db->get();
        $rows = $query->result_array();
        return $rows;
    }

When i change the where() statement to add FALSE as a second parameter, I get this error:

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '0' at line 3

SELECT * FROM (`coupon`, `users`, `organizations`) WHERE `coupon`.`coupon_user_id` = 3 AND users.user_id = 3 AND coupon.coupon_organization_id = 1 AND organizations.organization_id = 1 0

See that trailing zero? without it, the query works fine, I can't figure out where that's coming from!!

Any ideas?

Whoop, I seem to have fixed it. Found a data problem and took out the "False" and it started working.
