unable to display values from array in a view

tried to pick the last_query, and the result is strange:
echo $this->anotherDb->last_query();
die();

SELECT `payment_amount` FROM `payments` WHERE `payment_student` = '44' AND date_format(fee_month,"%d-%m%Y") >= date_format(curdate(),"00-%m-%Y") AND `payment_status` =0

Let me remove that date check too.
