Greetings!
Yesterday you guys taught me how to attach a DB and INSERT or REPLACE
records using the REPLACE command, which is soooooo much faster than for
each RECORD. Anyway, this update is client driven, so anyone of them could
hit the UpdateDB button at any time and, well, you know. So, since I have 6
clients, more soon, I want to make sure that I plan this right. What I
would like to know is, how do I know if I have a db attached already?
I know how to attach it with an uniqueDBID and since each client will update
their own unique ID, I know there won't be any collision for them. I am
also reading about UNLOCKED, SHARED, RESERVED, PENDING and EXCLUSIVE. Which
I know I will have to start playing with, because while a write is being
handle, someone may ask to read that RECORD that is being written and I want
to make sure that it is read after the write has completed.
Also, can different clients ATTACH to the same DB and REPLACE unique RECORDS
without any problem?
Any ideas?
thanks,
josé
