Potential Bug In ActiveRecord when doing compound join statement - El Forum - 12-03-2009

View Database Schema

Code:
$this->db->from('sales');

$this->db->join('sales_items', 'sales.sale_id = sales_items.sale_id');        

$this->db->join('sales_items_taxes', 'sales_items.sale_id = sales_items_taxes.sale_id AND sales_items.item_id = sales_items_taxes.item_id');

$res =  $this->db->get();

echo $this->db->last_query();

produces:

Code:
SELECT * FROM (`phppos_sales`) 

JOIN `phppos_sales_items` ON `phppos_sales`.`sale_id` = `phppos_sales_items`.`sale_id` 

JOIN `phppos_sales_items_taxes` ON `phppos_sales_items`.`sale_id` = `phppos_sales_items_taxes`.`sale_id` 

AND sales_items.item_id = sales_items_taxes.item_id

Notice how the second condition in the 2nd join doesn't have prefixes on the tables. Therefore the query fails. How can I achieve what I am trying to do?
