I was thinking that myself, but Patrick said that it was the "old" value which was being changed to the "new" value. Another trigger (a BEFORE UPDATE trigger), in a single update operation/chain, can only change the "new" value, nothing should be able to change the "old" value. Sean

Re: [firebird-support] After update trigger: the same values for new.somefiled and old.somefield
Would it be possible that the original update triggered a second update on the same record, hence the value of new and old are the same? For instance a trigger after update calls a procedure to update the same record, the first run of the trigger will have old <> new, but perhaps on the second run, triggered by the SP, the value of old would be the new value on the first execution of the trigger, and the value of new on the second execution may be the same as old if that field has not changed on the SP.

[firebird-support] After update trigger: the same values for new.somefiled and old.somefield
Hello, shouldn't the values of new.somefield and old.somefield be different in an after update trigger, when the value of that field has definitely changed? For some reason they both have the new value and I can't figure out why. If I didn't misread all the articles, I've found, completely, then they should be different, shouldn't they?

Error 10054 is "Connection reset by peer", which means that the server
tried to do something with the network connection from a client, and it
was already closed. This can happen due to network problems, or the
application was terminated abruptly. However the usual main cause is
that connections aren't properly closed, either by your applications (eg
you never close connections, and they are eventually terminated by the
garbage collector), or maybe by the driver you use (eg because its
implementation of a connection close is wrong).

> 2 -1 1 0 1 26 0023:0004
Assuming the normal order of columns in MON$ATTACHMENTS:
This is transaction 648583083 of attachment 84322, in state 0 (active),
it has READ_COMMITTED_VERSION isolation, wait without timeout (AFAIK),
read-only, no autocommit, with autoundo.
Maybe the associated attachment got terminated abruptly and Firebird
hasn't yet detected this and rolled back the transaction (or in this
case as it is read only: committed it). If you want to speed it up: a
restart of the Firebird server process would mark it as such IIRC.
