Hi All...
I'm been fighting this problem for a few days now, and it seems like it
should be simple. But the solution has eluded me so far...
I need to flag a record when it is updated or when it is a new insert.
Then I SELECT for the changed records and do something not related to
Postgres. Easy enough, I created a trigger procedure and fired it on
INSERT OR UPDATE and modify NEW to set the flag field to true.
But then the problem is how do I reset the trigger? If I do an UPDATE the
trigger fires again. I thought I could check for the flag field being NULL
and that works for an INSERT, but apparently if it is an update NEW
contains the existing value of the field.
I am trying to avoid modifying the cost the needs to set the flags (I can
change the schema), but I have full control over the code that has to reset
them. Is there a way I can update a record without firing the trigger, or
by bypassing it? This is a multi-user environment, so I can't really drop
the trigger and readd it.
Is there a solution not related to this?
I would appreciate some help, thanks very much!
