Re: Re: Using Random Sequence as Key

It is a good way to solve it but since I don't want/can't use cookies in my
application I could use only the random key but it would have to be unique
or the where key=$key could refer to multiple lines or I would have to ask
for the user to input both the random and the serial number wich wouldn't be
very good either. That's the reason I've being trying to make a random key
wich would be unique so I could ask for the user to type his order code and
then select info from orders where ordercode=$ordercode and not have the
risk of getting multiple answers (more then one line with that ordercode) or
someone typing his ordercode-1 and accessing someone elses form.

Do you have users logging in so that you know who is requesting the
data? If so, just make a view that includes WHERE name = current_user
to filter out all irrelevant (i.e., other people's) rows (inserts
should set name to the appropriate user, of course). In that case a
SERIAL will work fine, since there is no chance of seeing anyone
else's information and the SERIAL is unique. More secure, also.
