hi all i created a function that restarts the server, i will show you
what i am doing
drop trigger lala_trig on favorites;
drop function fav_funct() cascade;
create or replace function fav_funct() returns trigger AS '
declare
old_id int default 0;
new_id int default 0;
rec record;
rec2 record;
rec3 record;
BEGIN
select into rec max(id) as max_id from favorites ;
IF rec.max_id IS NULL THEN new_id :=1;
ELSE new_id = rec.max_id;
END IF;
select into rec2 max(id) as cnt from favorites where id = (select
max(id) from favorites);
select into rec3 count(*) as call_cat from call_cat ;
IF rec2.cnt < rec3.call_cat THEN new_id := rec.max_id;
ELSE new_id := rec.max_id +1;
END IF;
insert into favorites (id) values (new_id);
RETURN NEW;
END;
' LANGUAGE 'plpgsql';
create trigger lala_trig before insert on favorites
for each row
execute procedure fav_funct();
insert into favorites (call_cat_id,details) values (1,'1');
--------------------------- NOTE ---------------------------
I know this function sux but i am currently developing :)
----------------------------------------------------------------
test=# insert into favorites (call_cat_id,details) values (1,'1');
server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request.
The connection to the server was lost. Attempting reset: Failed.
