Re: function return value inside a trigger function

sorry for the late update

thank you all,

I found the cause, that specific sentence was correct,  it was in another sentence of the same function, I think it was late at night and I was tired.

 

thank you anyway

best regards

Works for me ...

create table fooey (q1 int, q2 int);

create function myt() returns trigger language plpgsql as $$
begin
  select abs(new.q1) into new.q2;
  return new;
end$$;

create trigger mytrig before insert on fooey for each row
  execute procedure myt();

insert into fooey values(-42, 77);

select * from fooey;
 q1  | q2
-----+----
 -42 | 42
(1 row)

Perhaps you should show a full example of what you're doing.
