Calculating overdue fine

Recommended Posts

Hello all, I’m using oracle 10g forms builder to create dvd rental system, the problem I’m having is calculating the overdue fine. I already have the date the dvd is rented out, $$date$$, and the date due, sysdate + 7 (i.e. 7 days after date out), i however as perversely stated have no idea how to calculate the fine (which is charged at £2.00 a day) and any help would be appreciated. Thanks, CaesarII

I forgot this is in the sql forum so the if becomes a WHERE. So, your code would look something like this:

"UPDATE table SET fine = 2 WHERE TIMESTAMP(NOW()) BETWEEN TIMESTAMP(rental_date) AND TIMESTAMP(WEEK,1,rental_date) AND customer_id = '$customer_id_selected"
