Chris, sorry. It's O-racle. I almost always state that, but I was more focused than I should've been on the particular code on the screen. Blinking more probably would've helped.
OK, so just to be sure that I understand. Here's a few tables below. When I delete a poll, this'll delete the associated answeres automatically and because they're deleted, any results
associated with those answers will also automatically be deleted - just be deleting a particular poll, right?
Tables:
<!--- the poll info, yknow --->
create table fsnep_polls (
p_id NUMBER Primary Key,
p_date_added date,
p_date_last_used date,
p_question VARCHAR2(400),
p_status NUMBER
)
<!--- all possible answers for any poll available --->
create table fsnep_pollAnswers (
pA_id NUMBER Primary Key,
pA_pollID NUMBER REFERENCES fsnep_polls(p_id) ON DELETE CASCADE,
pA_answer VARCHAR2(400)
)
<!--- all votes with their poll and answer ID --->
create table fsnep_pollResults (
pV_id NUMBER Primary Key,
pV_date_added date,
pV_poll_id NUMBER REFERENCES fsnep_polls(p_id),
pV_poll_Answer NUMBER REFERENCES fsnep_pollAnswers(pA_id) ON DELETE CASCADE,
pV_ip VARCHAR2(20)
)
I appreciate the answers and the help.
