In my opinion 'PessimisticLocking' is a fine feature of IB_Query,
because it says the users, that someone is already editing the record
BEFORE he starts to edit the record. I only wonder, why this feature is
not property of a Interbase-Transaction, because I don't think it's very
userfriendly, to say a user AFTER editing a record, sorry someone was
faster, try it again later.
The developers of Interbase will surely thought about that and they
decided not to implement it. But I don't see the reasons for this, can
anybody explain it to me ?
