Subject Newbee to events - how to know which record changed
Hi All,

I'm starting to use events for the first time, and decided to start by
experimenting on our inhouse bug tracker.

First project - trigger an event when a task has been completed, then
detect this event and mail the appropriate people.

Thanks to the info from Helen's trusty "The Firebird Book" I have put
the following code in the Before Update trigger on my Tasks table:

if ((old."DateTested2" is null) and (New."DateTested2" is not null))
then
post_event 'task_completed';

Next I fired up my Delphi, and added the components to detect the event,
but all I have available to me is the event name, and a counter.

My question is, how do I know what record triggered the event? Is there
any way of passing additional data through to the application?

If I do a query for all tasks completed today, I'll possibly get more
than one back, and the list will get longer as the day goes on.

I presume I need to have some kind of an event logging table and insert
the relevant information in there. In which case, I don't even need
events at all anyway?? (OK, maybe just one event on my EventLog table
every time a record is inserted to save me polling it periodically)

I'm getting the feeling I might be missing the whole point of Firebird
events?

Thanks
Maya
