Hello people,
I am working on a trouble ticket system in Perl, usually those systems
identify a ticket by a string composed of DDMMYYYY-SERIAL, (DD = day,
MM= month, YYYY= year, SERIAL= a serial number for the date string).
I am not sure how to generate these identifiers, in case I generate
them manually i must provide a mechanism to insure the sequence, like
locking the table for reading/writing, get the last value, insert the
new one and then release the lock. However i think this could be a big
performance killer. Any ideas?
The other option I see, is creating a user defined type that will take
care of keeping the sequence for me. I read the apropiate page at the
programmers manual, but i think i would need more information. Any
resources?
Regards,
Juan Jose
