Greetings all,
I *think* there¹s a way to accomplish what I want, but it is eluding me at
this time. Any help or pointers will be greatly appreciated.
What I am trying to accomplish is that when a member deactivates their
account through the UI, my trigger will call a function that deletes or
archives their data. The issue being that we don¹t want the UI to have to
wait for this process because of the huge amount of data and tables that
the queries will have to go through, so we are avoiding doing it
programatically through the UI and I want it to happen in the background.
The problem is this (and I may just not be thinking clearly): Everything
is tied back to the member¹s ID which is the constant throughout the
tables that I will need to manipulate. My trigger will call the (to be
written) function that will do all the heavy lifting when the
active_status changes from Œa¹ to Œx¹, but I somehow need to get the ID of
that member and pass it on to the function so it can then do all that it
needs to.
For simplicity, the member table is just a few columns (id, active_status,
name). How would I grab the ID from that table the moment the trigger
fires to be able to pass it to my function?
I hope that¹s clear.
Thanking you in advance for any help.
Something more concrete assuming using plpgsql Also just a skeleton
function to demonstrate fetching id.
CREATE OR REPLACE FUNCTION status_update()
RETURNS trigger AS
DECLARE
m_id int;
$Body$
BEGIN
IF NEW.active_status = 'f' THEN
m_id := NEW.id;
<more code>
END IF;
RETURN NEW;
END;
$Body$
LANGUAGE plpgsql;
