Help with Binding

Hope this work.
$ncCouponQuery = $this->db->select('*')
->from('coupon_master')
->group_by('coupon_master.ID')
->join('coupon_analytics','coupon_analytics.CouponID=coupon_master.ID')
->get()
->result();
$count= count($ncCouponQuery);

Thank very much. This is basically what I was looking for so I can use this as a template to work with more complex queries. The guide shows basic examples.

Again, thank you.
