If you remove the second select statement it compiles and runs fine. That was exactly the issue I was pointing out. You are using SELECT without INTO to call SendMail. That doesn't work as Sean also pointed out. Furthermore, invoking that Sendmail procedure as a select procedure is not sensible in this environment or any other. Make it an executable procedure and, in the trigger code, call it with EXECUTE PROCEDURE (:var1, :var2, etc.) Selectable procedures are intended to return sets and shouldn't be used to execute DML. Helen, it was actually a singleton select against RDB$DATABASE calling the SendMail UDF in the column list.
Re: [firebird-support] nbackup failure - cause?
the level 0 backup restores ok and gbak will then backup restore that, could the corruption be somewhere that that doesn't matter? how can I find and deal with it?

[firebird-support] Questions about nbackup
I have been looking into switching from gbak to nbackup. From what I have read about nbackup I am left with some, possibly incorrect, impressions. 1) nbackup is a page level backup rather than a row-by-row backup like gbak. 2) nbackup does no integrity checking of the database as it is backed up. It simply copies the database page by page. 3) If 2) is true, then this would seem to imply that I could back up a corrupted database using nbackup without ever knowing that the database was corrupt. 4) If 2) 3) are true this would seem to imply that I could restore a corrupted database using nbackup and wind up with a corrupted database, the same as the original. Please feel free to correct my misconceptions.
[firebird-support] Re: Handling deadlocks with classic mode
Ann, Thanks for the suggestion. If I can tie a deadlock to a process ID, that will work out great. I was intimidated by the lock manager before but after looking at its printout again, it doesn't seem that bad. Thomas, We do not have SysInternals ProcessExplorer on our server, but I see that it is freely available so we will shortly. Thanks to all for your help. I think I have enough information and tools now to solve my Firebird issues. Regards, vince --- In firebird-support@yahoogroups.com, Ann Harrison aharrison@... wrote: Vince, Thanks for the response. We are running Windows. I'm not sure how much information about the fb_inet_server processes I can gather -- other than how long they've been running. Not sure how to get the IP address of the connecting client. I'm going to just start killing the oldest fb_inet_server processes, but I don't know how I can distinguish the listener process. If I kill that one by mistake, I guess I'll have to reboot the whole server because I don't know how to restart just the listener. Is there a way to identify the listener process? Get a full lock print, find the deadlock, find the owner block for the deadlocked resource, and you'll find the process id of the listener there. Helen's book describes the contents of the lock print. Good luck, Ann [Non-text portions of this message have been removed]

In general, you are right.
