Hi Adrian,
I want the trigger function to insert a row in cf_user_question_link
table with fields as show in the function once the there is a insert
from in the cf_question table.
If so and I think this was mentioned before, why the UPDATE in the
trigger statement?
I know 94 = 1 + (3 * 31).
I am just having a normal insert statement into cf_question table.
Are there any other triggers on the tables?
regards
Kiran

Dear Folks,
I have a table *cf_question *with 31 rows.
I want to insert/update another table *cf_user_question_link* when
cf_question table is inserted/updated with row(s).
I have written trigger function for this as follows.
CREATE FUNCTION user_question_link() RETURNS trigger AS
$user_question_link$
begin
SET search_path TO monolith;
INSERT INTO
cf_user_question_link(cf_user_id,cf_question_id)
VALUES(NEW.user_id,NEW.cf_question_id);
RETURN NEW;
end;
$user_question_link$
LANGUAGE plpgsql
COST 100;
/* Call the trigger function */
CREATE TRIGGER insert_user_question_link AFTER INSERT OR UPDATE
ON monolith.cf_question
FOR EACH ROW EXECUTE PROCEDURE user_question_link();
In addition to what Alban said:
What do you want the trigger function to do ?
In other words what are the condition(s) that are supposed to create
a new row in cf_user_question_link?
Problem: The *cf_user_question_link* gets inserted with 94 rows
instead
of 31 rows. The 31 rows are repeated 3 times
Well actually 1 row + (3 * 31 rows).
So what is the query you are sending to cf_question?
I tried dropping the trigger function and
recreating it
but with the same 94 rows in the table.
It would be great if any from the forum point to me where I am
doing wrong.
regards
Kiran
