By this i get ID of customer table but i want to get both table unique ID

Answer 1

Create a relation in between Customer & CustomerPlan.
You can create a relation in model relations function.

Public function relations()
{
   return array(
      'customerPlan' => array(self::HAS_MANY, 'CustomerPlan', 'cust_id'),
   );
}

Now use this relation to find out related records:

$criteria->with = array('customerPlan');

Get the relational records of Customer model:

$customer->customerPlan
